Many natural ecosystems have been destroyed by human activity. To better manage our remaining natural ecosystems, we must first understand how the ecosystems are structured. One way to do this is to determine how the organisms in the ecosystem obtain the matter and energy they need to survive. The figure below shows a simplified food web. Use the figure to answer the following questions.


Which of the following correctly shows one pathway for the flow of energy to an owl?

Explanation:

costal marshes are where high level of other life like fish and insect are

A is incorrect. This sticking together of like substances is called cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be more or less cohesive. Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.

B is correct. The property in which water molecules stick to one another tightly. The property in which water molecules easily evaporate into a gas.

C is incorrect. In cohesion, water molecules are attracted to each other (because of hydrogen bonding), keeping the molecules together at the liquid-air (gas) interface, although there is no more room in the glass.

Answer: the rate of pollination of flower, in a field next to a pond with no fish, will DECREASE.

Explanation:

POLLINATION is defined as the process by which flowering plants, through the aid of external agents such as insects,wind, water and other animals, are able to transfer pollen grains from an anther to a receptive stigma. Insects are the most common pollinators. They visit flowers to obtain nectar and pollen as source of food. Flowers use various features, such as colour and scent, to attract and guide insects to the food source within them. In the process of reaching their source of food, insects bring about pollination.

From the study conducted by scientist in Florida, eight(8) ponds where subjected to the the study. The first four (4) ponds had species of fishes that fed on dragonflies and dragonfly larvae, hence the reason for a decrease in the population of the dragon flies in the area around it. While the remaining four (4) ponds had NO fish and the area around it is populated with dragonflies and dragonfly larvae. This is so because of the absence of fish.

It was then noted that the dragon lies fed of the insect pollinators such as the bees and butterflies. Since these dragonflies and its larvae are abundant in the field which is close to the pond with no fish, they will grossly depend on the insect pollinators as their source of food thereby decreasing the rate of pollination in the field next to the pond with no fish.

Answer:

maybe beacuse there not enough water and its too hot the sun will dry them up

Explanation:

Answer:

Because the ground is not fertile.

and there is too much of sunlight.

Answer:

B. the presence of cyclic AMP and lactose

Explanation:

Maximal transcription of the lac operon requires the presence of cyclic AMP and lactose. Cyclic AMP/CRP complex attached to a specific sequence in the lac control region. This region is known as the "CAP" site. Mutations that occurs in the CAP site prevent cyclic AMP-CRP binding which also prevent high levels of expression of the lac operon. The lac repressor and catabolite activator protein (CAP) are the two regulators that is responsible for turn on and off the operon in response to lactose and glucose levels.

Answer: A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

Answer:

Explanation:

A coral reef is an environment in which various abiotic (water, sunlight, temperature, salt, waves, and so on) and biotic (aquatic plants, shrimps, fish, corals, and so on) factors combine to maintain the system's homeostasis. A simulation model is a descriptive model that makes future inferences about one system using existing data (or process). A computer-based experiment in which each part of the device contributes to the measurement of the impacts induced by the interaction of unknown inputs is also known as a simulation model. It is possible to determine how changes in water temperature influence the relationship between various types of trophic levels in the coral reef environment, which may be expressed by aquatic plants and fish species, by using a simulation model.

Corals, algae, and fish in coral reefs have a lower survival rate as the pH of the ocean water drops. In acidic ocean water, coral reefs struggle to survive. This is due to the coral's calcium carbonate shell's inability to withstand an acidic environment. Snails, clams, algae, fish, and other animals have calcium carbonate in their skeletons. The death of these animals is caused by increased acidity. As a result, the lower the pH of ocean water, the higher its acidity, and therefore the lower the chance of corals, algae, and fish surviving in the coral reef.

The amount of calcium carbonate in coral reef water is affected by a lower pH value (more acidic). Since coral skeletons are made of calcium carbonate, this has an effect on them. It may be a major issue (since coral reefs are a source of food and tourism), since it would be more difficult for them to calcify or even dissolve. As a result, if 'ocean acidification' occurs as a result of carbon dioxide absorption from the atmosphere, reduced pH may reduce coral reef biodiversity.

The simulation's pH is too low to allow coral reefs to develop. The ocean is affected, and these coral reefs are important for the diversity of marine life because they have a lot of nutrients, which is ideal for small organisms to live in. As a result, if there is a lot of acid in the water, these coral reefs will dissolve and vanish.

I'd raise the ocean's temperature and lower the pH percentage so that users can see how human activity affects the ocean. Human activity causes contamination of the air, which causes CO2, which causes more of the CO2 to be consumed by the seas, raising acidity, which contributes to an increase in temperature and the dissolution of coral reefs.

Add mutations, edit genes, pick factors such as wolves, food, climate (arctic or dessert), and monitor population or pedigree chart were some of the variables I had control over in the simulation.

The impact on the pH of Earth’s oceans can be reduced by lowering the carbon dioxide in the air, and reducing the plastics that goes into the oceans.

Government-approved projects will be needed to temporarily limit fishing in the region. There will be a dead end in seafood resources from the river as a result of the consequences.

Answer:

Animals are less likely to eat the plant

Explanation:

It tastes bad so they wont want to eat it again

Animals are less likely to eat the plant and It tastes bad so they wont want to eat it again.

The process by which organisms adapt to their environment in order to increase their chances of surviving in that environment is known as evolutionary adaptation, or simply adaptation.

The biological process through which organisms adapt to brand-new surroundings or alterations in their current environments is known as adaptation.

Wallace and Darwin both went beyond basic adaptation when formulating the notion of evolution by natural selection by describing how organisms adapt and evolve.

Therefore, Animals are less likely to eat the plant and It tastes bad so they wont want to eat it again.

Answer:

B

Explanation:

Answer:

N (t) = 788 individuals

Explanation:

There are some parameters to consider when analyzing the evolution of a population in time regarding its size. Some of them are the generational time -T-, the intrinsic growth rate per capita -r₀-, the net reproductive rate -R₀-, the reproductive value -V₀-. among others.

To obtain the net reproductive rate -R₀- of a population, we must relate the contribution of individuals of each age to the next generation, with the possibility that those individuals reach that age.

It can also be considered the media of female offspring that each female can produce throughout its whole life.

You can also think about it as a quantity by which the population abundance will increase, decrease, or remain the same in the followings generations. And this concept is related to what is stated in the problem.

According to the given information, we can use different formulas to calculate R₀

R₀ = N(t) / N(0) ------> (N0 being the population size at time zero, and Nt in a

                                    certain generation)

R₀ = sum (lx * mx)---> (Lx being the survival rate and mx the fertility rate)

-------------------------------------------------------------------------------------------------------

To answer this question, instead of calculating the R₀ value, we need to calculate Nt, which is the population size at t generation. In this example, is the following generation, so t=1.

We already know that N₀ = 788 individuals and that R₀=1.

By clearing the equation R₀ = N(t) / N(0), we can get the Nt value.  

N (t) = N₀ x R₀

N(t) = 788 x 1

N(t) = 788 individuals

The population size at time 0 and time 1 is the same. This is because the R₀ value = 1, meaning that the population is in equilibrium. It does not increase either decrease. Probably there are as many deaths as births.

Answer:

Slow down the break down of carbohydrate.

Explanation:

Hydrolysis of the carbohydrates will be affected if a person’s salivary glands were unable to produce saliva because saliva has enzyme that speed up the digestion rate of carbohydrates. If the saliva did not produced by the organism's salivary glands, the hydrolysis or break down of the carbohydrates   did not occur in the mouth and as a result the body takes more time for the complete decomposition or break down of carbohydrates.
