Answer 1
Answer: A forest ecosystem can support a limited number of bears. This is because available energy is lost from one trophic level to the next. (flies, trout, then bears)
Answer 2
Answer:

Answer:

The correct answer would be C)  available energy is lost from one trophic level to the next.  

It is the universal law that the energy is lost when transferred from one trophic level to the next.

It is because most of the energy present at any trophic level is used by the organisms for their biological processes such as locomotion, reproduction et cetera. Due to this, most of the energy is lost as heat in the surrounding environment.

In the given food chain, the bears are present at the highest trophic level and thus they would get minimum energy.  

Thus, the ecosystem can provide only a limited amount of energy to the bears due to which the ecosystem can support a limited number of bears.

Which statement is one component of the cell theory? All living and nonliving things consist of one or more cells. Cells and living organisms are spontaneously created. Cells are the most complex unit of structure and function in living things. A cell is the basic unit of structure and function of all organisms.

Answers

One component of the cell theory is A cell is the basic unit of structure and function of all organisms. Thus, option "D" is correct.

What is cell theory?

The cell contains genetic material in the form of DNA which is passed from the parent cell to the daughter cells after cell division.

All cells are similar in chemical composition as well as in metabolic activities.

All the physiological and biochemical functions usually take place inside the cell.

The activity of the cell depends upon the cell organelles and other cellular parts.

Thus, option "D" is correct.
