A population of 95 peregrine falcons are the primary predators of a local pigeon populations. The pigeons have a population size of
1,300 and a birth rate of 0.38 per year. The predation rate of falcons
on pigeons is 0.004, and the falcons have an efficiency rate of
0.0002 per prey. A population of 10 eagles are the main predator of
the falcons with a predation rate of 0.002 and an efficiency rate of
0.0003. How many peregrine falcons do you expect to observe in
this population one year from now? Assume that all falcon deaths
result from being eaten by eagles and that all falcon births rely on
falcons eating pigeons. Round your final answer to the nearest whole
number.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.

if you know your abc's you should be able to get your answer or just use google

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
