What interaction is there between the brown tree snakes and the birds, lizards, and bats?
Answer:
Predatory.
Explanation:
This is because the tree brown snakes feed on birds while the bats feed on the lizards.
This is so that the bats can eat lizards while the tree brown snakes can eat birds. The brown tree snake bites and grips its victim to paralyze it.
What is predatory behavior brown tree snakes and other?The predators of the brown tree snake are not widely known. According to some research, monitor lizards, feral pigs, and cats prey on brown tree snakes, and other.
Investigations have revealed that the species is also vulnerable to red-bellied black snakes and cane toads.
The snake encircles its victim's body with its own and begins to chew, allowing its teeth with grooves to release venom into the area.
Since mammals are less susceptible to the venom's effects than other animals, it is considered to be rather moderate.
Therefore, predatory interaction is there between the brown tree snakes and the birds, lizards, and bats.

In an Antarctic pelagic community, the primary producers are phytoplankton, which serve as food for the dominant grazing zooplankton, especially krill and copepods, both of which are crustaceans.
These zooplankton species are in turn eaten by various carnivores, including other plankton, penguins, seals, fish, and baleen whales. Squids, which are carnivores that feed on fish and zooplankton, are another important link in these food webs, as they are in turn eaten by seals and toothed whales (Figure 1).
Figure 1: Arrows follow the transfer of food from the producers (phytoplankton) up through the trophic levels. For simplicity, this diagram omits decomposers.
Antarctic krill (Euphausia superba) is an important source of food for whales, seals, squid, fish, and many species of birds. Its abundant biomass is one of the largest on Earth. Figure 2 compares the effects of krill harvesting on species richness within two small sections of the Antarctic region; one section was subject to krill harvesting and the other section was not.
Describe how the autotrophs facilitates the flow of energy through the Antarctic ecosystem. In the Antarctic pelagic community, there are three types of seals. The leopard seals eat birds, but the crabeater and elephant seals do not. Explain how the interactions between seals and other species may affect their food sources.
Identify the independent variable of the data graphed in Figure 2. Explain one way this variable is affecting the biodiversity of the Antarctic food web.
Analyze the change in species richness with or without krill harvesting. Predict how the removal of krill from the Antarctic ecosystem will affect its long-term structure.
Justify the claim that the Antarctic krill is a foundation species, not a keystone species. Provide evidence to support your claim.
Answer:
a) the autotrophs produce their own energy in their system and synthesize surrounding energy, which allows for the flow of energy as they are the primary producers at the bottom of the food web shown in figure 1 who transfer and facilitate their energy when they are consumed by the organisms in higher levels. This facilitation of energy continues where the population of these autotrophs is stable and the cycle of consumption and synthesis of energy from one trophic level to another and there is a diverse amount of energy distributed in the ecosystem. The leopard and Elephant seals have a similar food preference which may cause competition for resources in the ecosystem between the two more than that of the crabeater seal as they rely solely on krill in the ecosystem to survive. If there was more competition for the krill or a decrease in population, their population is sure to suffer as well.
b) The year is independent of the number of species in the data graphed. This variable affects the biodiversity in the food web where we witness the number of species (hundreds) likely to witness an increase over time when krill are harvested and a decrease in the number of species without krill harvesting. This, in turn, may prove that krill is a keystone species crucial in the food web and ecosystem where the antarctic krill population's presence will influence the number of species as well.
c) The changes in species richness with krill harvesting, as per mentioned, will show an increase in species number as the krill's energy is transferred throughout the ecosystem by consumption, as implied in the food web. The changes in species richness with a lack of krill harvesting, or some organisms unable to consume the energy of the krill, was shown to have a decrease in species # over the years. This will affect the long term structure of the ecosystem as the organisms who rely on krill and even those in the trophic levels which rely on species who consume krill will drop dramatically, and the lowering of the number of organisms in a keystone species will cause a decrease in speciation of the ecosystem (possibly quite rapidly due to the dependence we witness on it) as well as a disruption in the energy flow.
d) we can affirm that the krill are in fact not a foundation species, but a keystone species as they show no specific traits of facilitating the populations of the species in the ecosystem, and don't appear to benefit other species in the ways foundation species do (ie. they are autotrophs and cannot provide shelter for other species, but we can also say that they are the sole energy producers for the crabeater seals, which can be a trait of a foundation species)- instead exhibiting the traits of a keystone species as they produce an abundance of energy in the ecosystem and the removal of them (as shown in figure 2), causes a population decrease all around.
Explanation:
ur welcome i just did this myself so pls paraphrase as much as u can also like a bit of an explanation its kinda obvious from the chart that they all rely on the krill and stuff so removing it (or not harvesting or something) would be bad. again pls paraphrase as much as u can and good luck

Which of the following could limit the growth of a population of squirrels in a local park?
A. Increase in the number of trees preferred by the squirrels for nests
OB. A decrease in the number of hawks, which prey on squirrels
C, Heavy rain causing an increase in acorns that the squirrels eat
OD. An outbreak of a disease that infects squirrels in the park
Answer:
D
Explanation:
They would be dying off, or leaving to get away from the disease
An outbreak of a disease that infects squirrels in the park could limit the growth of a population of squirrels in a local park. As the disease spreads and more squirrels become sick or die, the population growth rate will decline and may even become negative, leading to a decrease in the overall population size. Hence option D is correct.
What is an infectious disease?An infectious disease is a type of illness that is caused by a pathogen, such as a virus, bacterium, fungus, or parasite. These pathogens can enter the body and cause harm by multiplying and damaging the host's tissues.
Infectious diseases can spread from person to person, through contact with contaminated surfaces, via airborne particles, or through the bite of an infected animal. Some examples of infectious diseases include influenza, HIV/AIDS, tuberculosis, malaria, and COVID-19.
When an infectious disease spreads in a population, it can weaken or kill members of that population, thus decreasing the overall population size. The spread of the disease may be more rapid and widespread in populations that are densely packed, such as the population of squirrels in a local park.
The disease could be caused by a pathogen, such as a virus or bacteria, and could spread through direct contact or through contaminated food and water sources.
Hence option D is correct.

Together, the stages of cellular respiration break down one molecule of Choose... to generate a total of Choose... molecules of ATP. The remaining energy is released as Choose... .
Answer: 1) Glucose
2) 36
3) Heat
Explanation: Cellular respiration is a metabolic process that every living organism undergo. It is the process by which energy is obtained by living cells. In the process of celluar respiration, energy-storing food molecule called Glucose is broken down in the presence of oxygen in order to release its energy and convert it to a usable form by the cell called ATP.
Celluar respiration occurs in three distinct stages in eukaryotes viz: Glycolysis Kreb's cycle and Oxidative phosphorylation. In Glycolysis, which occurs in the cytoplasm, glucose is broken down in a series of enzymatic reaction to yield Pyruvate and releasing a net gain of 2 ATP molecules. In Kreb's cycle, which occurs in the mitochondrion, produces carbondioxide in a two-cycled reaction involving Pyruvate. 2 ATPs are also produced in this stage.
Lastly, in Oxidative phosphorylation also occuring in the mitochondrion, electrons are passed through electron acceptors to create a pump that generates the synthesis of 32 ATP molecules. In general, the three stages yield a total of 36ATP molecules from one molecule of GLUCOSE.
The rest of the energy from the oxidation of glucose is lost as heat energy, which is responsible for the warming effect we feel. braibnliest??

Answer: 43. Erosion breaks rocks down further and then moves them. Forces like wind and water move the rock pieces. They mix with matter like sand to become sediment. Weathering and erosion help shape Earth's surface. 44. After compaction and cementation the sedimentary sequence has changed into a sedimentary rock. Sedimentary rocks like sandstone, shale and limestone differ from other rocks in that they: 1. Are formed from layers of sediment built up over many years. Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock. 45. metamorphic rock. 46. igneous or sedimentary rock. 47. Similarly, liquid magma also turns into a solid — a rock — when it is cooled. Any rock that forms from the cooling of magma is an igneous rock. Magma that cools quickly forms one kind of igneous rock, and magma that cools slowly forms another kind.
