In the diagram we see a cell plant, with a few structures numbered:
0. Vacuole
,
1. Chloroplast
,
2. Nucleus
,
3. Cell wall
The answer options correspond with the functions of these structures:
0. Vacuole- Has secretory, excretory, and storage roles (B)
,
1. Chloroplast - It makes the photosynthesis (D)
,
2. Nucleus - Serves as the control center of the cell and contains the genetic information (A)
,
3. Cell wall ,- ,Provides structural support to the cell (C)
If CO2 was in very small amounts then it would be the limiting factor of photosynthesis, this means the process will take place at a much slower rate
Energy is catch by producers then given in a linear
progression from one tropic level to the next. At each level, much of the
energy escapes the ecosystem as heat. Unlike this one-way flow of energy,
matter is recycled within and between ecosystems. Elements passage from one
organism to another and among parts of the non-living environment through
closed loops called biochemical cycles.
B???????????????????????????????????????
Answer:
2 and 3
Explanation:
1 is incorrect because A does not seem to have a predator-prey relationship but C does
2 is correct because of the increase and decrease does indicate the predator-prey relationship B and C have
3 is correct because the over time the population remains the same since it is not harmed by B and C
4 is incorrect because if A was harmed by B and C, the population should decline.
