Question

env4. in a food web that consists of grass, mice, deer, coyotes, and hawks, which species is likely to have the greatest biomass?
env5. the number of organisms that an environment can support is called -
life expectancy
carrying capacity
growth rate
denography
env6. an example of a density - dependent limiting factor is -
the amount of available food
a sudden flood
a decrease in water due to drought
an avalanche

Explanation:

• For the first question, in a food - web with grass, mice, deer, coyotes, and hawks, hawks are at the top of the food - chain and have the greatest biomass as they are the top predators.
• For the second question, the number of organisms that an environment can support is called the carrying capacity. Life expectancy is related to the average lifespan of organisms, growth rate is about how quickly a population grows, and demography is the study of population statistics.
• For the third question, a density - dependent limiting factor is one that is affected by population density. The amount of available food is density - dependent because as the population density increases, the competition for food increases. Floods, drought - related water decrease, and avalanches are density - independent factors as they affect populations regardless of their density.

Answer:

• ENV4: hawks
• ENV5: carrying capacity
• ENV6: the amount of available food
