why cant food chain be indefinitely long
Answer:
Because:
Explanation:
Some energy is lost gradually in several ways at each trophic level:
Energy is lost through respiration, generating heat at each trophic level.
Energy is lost through waste (waste through excretion, feces, leftovers, etc. or energy lost through shedding of leaves in plants, shedding, molting of animals, ..) at each trophic level.
The higher the food chain (or trophic level), the less energy accumulates and to a certain extent there is no longer enough to maintain a link (of a trophic level). When a link (actually a species or group of card fish of a species) has too few individuals (smaller than the minimum size of the population) will not exist.

The diagram illustrates plants and two different zones of a deep lake.
In the upper part of the photic zone, organisms carry out both photosynthesis and cellular
respiration. Deep in the aphotic zone, only cellular respiration occurs.
Which statement is the most likely reason photosynthesis does not occur in the deepest
aphotic zone?
A)Sunlight for photosynthesis does not reach the deepest aphotic zone.
B) Water pressure limits the survival of animals in the deepest aphotic zone.
C) Not enough soil is present to support plant growth in the deepest aphotic zone.
D) Not as much dissolved oxygen from the surface reaches the deepest aphotic zone.
Answer:
A
Explanation:
B, C, and D all don't make sense, B doesn't talk about photosynthesis at all, same for C and D.
For photosynthesis to occur sunlight is of utmost importance. Therefore, option (A) is the reason why photosynthesis does not occurs in aphotic zone .
What do you understand by aphotic zone ?
The vast majority of the ocean's water may be found in the zone that is the deepest and darkest, known as the aphotic zone. This zone is directly below the photic zone and is characterized by its absence of light.
In the aphotic zone, there is not a single viable plant to be found. In the aphotic zone, there is no exposure to sunlight. Because they need light to create their food from carbon dioxide and water, plants are unable to live in an environment that is devoid of light (the aphotic zone).
The aphotic layer encompasses around 90 percent of the ocean.
Therefore, option (A) that is sunlight for photosynthesis does not reach the deepest aphotic zone is correct.

Need help why are producers different from consumer and why are consumers diffrent from producers 5 paragraph summary
Answer: The producers generate food for themselves and others; consumers do not produce anything, instead eating producers, other consumers or both. Organisms that eat only producers (i.e., plants) are called herbivores. Animals that eat only consumers (i.e., meat) are called carnivores.
Producers are organisms that can make its own food while Consumers are organisms that obtain energy by feeding on other organisms. Producers are commonly called autotrophs. In the food chain, heterotrophs are primary, secondary and tertiary consumers. An Example of Producers are green plants. An Example of consumers are animals.

Why are forests important for helping to control the rate of climate change?
Answer: Forests are a stabilizing force for the climate. They regulate ecosystems, protect biodiversity, play an integral part in the carbon cycle, support livelihoods, and supply goods and services that can drive sustainable growth.
Explanation:
The forest helps to maintain ecological balance, carbon cycle and rainfall.
How forest maintains ecological balance?"Ecological balance is a state of dynamic equilibrium within a community of organisms in which genetic, species and ecosystem diversity remain relatively stable, subject to gradual changes through natural succession."The forest prevent soil erosion and maintain soil fertility. It establish oxygen and carbon balance in nature.It absorbs harmful gases like carbon from environment. What is carbon cycle?"The carbon cycle is biogeochemical cycle by which carbon is exchanged among the biosphere, hydrosphere and atmosphere of the earth."Forests takes up carbon from atmosphere and gives out oxygen.Forest helps in decay, disturbance and renewal of carbon.Hence, the forest regulate rainfall, ecological balance and carbon cycle.

C. Water near the shore of a lake becomes warmer on a sunny day.
O D. Water at the top of pan becomes warmer as water from the
bottom of the pan rises.
SUBMIT
Answer:
A
Explanation:
Conduction is the exchange of energy as warmth or power starting with one iota then onto the next inside an article by direct contact. Conduction happens in solids, fluids, and gases. Nonetheless, solids move energy most proficiently since the atoms in solids are most firmly stuffed, and the particles are nearer together, as displayed in this figure. For fluids and gases, the thickness of the particles are by and large lower than those of solids and the particles are farther separated, so the energy move is less productive.

n a simple food chain, wolves eat deer and deer eat shrubs. A pack of wolves has a total biomass of 1,000 kilograms. Approximately what biomass of shrubs must have been eaten by deer to support that wolf pack, assuming that only shrubs, deer, and wolves exist in the food chain
Answer: 100000 kg of biomass of shrubs must be eaten by deer.
Explanation:
According to the Lindeman 10% law :
When energy is transferred from one tropic level to another successive tropic level, only 10% of the energy gets transferred while the remaining is lost in the environment.
We are given:
Biomass of the pack of wolves = 1000 kg
This means that 10% of the biomass of deer is 1000 kg
Biomass of deer will be:
[tex]10=\frac{1000}{x}\times 100\\\\x=\frac{1000\times 100}{10}=10000kg[/tex]
Now, this biomass of deer is 10% of shrubs' biomass.
This means that 10% of the biomass of shrubs is 10000 kg
Biomass of shrubs will be:
[tex]10=\frac{10000}{y}\times 100\\\\y=\frac{10000\times 100}{10}=100000kg[/tex]
Hence, 100000 kg of biomass of shrubs must be eaten by deer.
How does the chain of amino acids determine the shape of a protein?
Answer:
ok mark me brainliest also have a good day
Explanation:
A protein's shape is determined by the sequence of amino acids that make up the protein. The order of the amino acids, or the primary structure, determines the folding of the amino acid chains or tertiary structure. The interactions between the side chains and the amino acids determine the folds of the protein. and The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape. ... The final shape adopted by a newly synthesized protein is typically the most energetically favorable one.

If oxygen is more concentrated outside a cell than inside
Answer:
What happens if the concentration of oxygen molecules outside the cell is lower than that inside the cell? Diffusion.....the oxygen molecules will move inside the cell until the concentration is equal inside and outside. Why do many cellular processes depend on osmosis?
Explanation:
Three common types of passive transport include simple diffusion, osmosis, and facilitated diffusion.
If oxygen is more concentrated outside a cell than inside diffusion will occur.
Oxygen is an element that is for cellular respiration which are metabolic processes that are essential for life.
A cell is the smallest and basic structure of organisms that is surrounded by a membrane.
Diffusion is the process by which molecules of a substance move from a region of where they are highly concentrated to a region where they are less concentrated.
Therefore when oxygen molecules is more concentrated outside a cell than inside, a concentration gradient exits between the inside and outside of the cell leading to diffusion of oxygen into the cell.
