The population of frogs would exhibit competition due to the limited resources in the lake. Competition can be defined as the interaction among the species of organisms when resources are limited in an ecosystem. The type of competition observed in the above example of the lake with limited resources is called intraspecific competition as it is between the members of the same species competiting for the same resources. The species that do not compete will eventually die or get eliminated. This results in the change of population of frogs over time. Thus, competition is one among the forces that is responsible for natural selection.
When acid precipitation occurs, it effects Earth in a few ways. One way is that when the acid rain soaks into the soil, it removes the nutrients that plants rely on. This, in turn, damages a lot of vegetation. Another way is that it raises acidity levels in water. The higher the acid levels, the more it harms the organisms living in water.
I think this sounds alright

The excretory system is intended to remove any solid/fluid waste from your body, such as urine.
Answer:
The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH
Photosynthesis is
6 CO2 + 6H2O---> C6H12O6 + 6 O2. So unless I understand the question wrong, none is needed to do, but glucose and oxygen are products after the photosynthesis
