Next to the food web, draw an ecological pyramid using the food web above and determine the biomass of the deer
if the wolf consumes 8943 kg. Label each trophic level in the pyramid.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

explanation:

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint

the answer would be   10%
