egoroff_w [7]

A student of ecology researched about the low growth of algae in the Big Moose lake as compared to the Brant lake, though Big Moose lake has higher  level of nitrogen and nutrients in it.

Nitrogen and phosphorous are an important element for the growth of algae in water bodies but in presence of pollutants in  the water bodies and low oxygen content, the algae grows in slower rate.

Answer:

They camouflage

Explanation:

The peppered moths adapt to their surroundings. They blend in with their surroundings to avoid being eaten by their predators. Blending in with their surrounding also helps them to sneak up on and catch their prey.

I'm not too sure why they lay 100 eggs at a time but i think it's because the parents want to increase the survival of their eggs. Eggs sometimes are eaten by other animals and the parents want at least a few to survive.
