Question

1. two species of birds move into the same area and both eat the same type of seeds. what are two possible outcomes of this competition? which ecological principle explains it? 6. describe what an exponential growth curve looks like, and what a logistic growth curve looks like. what causes the difference between the two shapes?

Explanation:

For question 5, one outcome could be competitive exclusion where one species out - competes the other and drives it to local extinction due to limited resources. Another could be resource partitioning where the species divide the resource in different ways to co - exist. The competitive exclusion principle states that two species competing for the same limiting resource cannot coexist indefinitely.
For question 6, an exponential growth curve is a J - shaped curve representing continuous growth without limits. A logistic growth curve is an S - shaped curve. Initially, growth is exponential, but as the population approaches the carrying capacity of the environment, growth slows and levels off. The difference is caused by environmental limitations in the case of logistic growth, while exponential growth assumes no such limitations.

Answer:

1. Possible outcomes: Competitive exclusion (one species drives the other to local extinction) and resource partitioning (species divide the resource to co - exist). Ecological principle: Competitive exclusion principle.
2. Exponential growth curve: J - shaped, continuous growth without limits. Logistic growth curve: S - shaped, growth slows as population approaches carrying capacity. Difference cause: Environmental limitations in logistic growth, none in exponential growth.
