Answer:

The likely explanation is that population 1 had traits which were more favorable to its survival than population 2's in the new conditions. It wouldn't have to do with food competition, but the traits they already have that may or may not be conducive to their survival in the new conditions.

Explanation:

Let me explain. Say a drought occurred on an island. Population 2 relied on eating bugs that lived in the green grasses. Population 1 relied on eating cactus fruit, which is drought-resistant. Say that because of the drought, population 2 started to decrease since there were less bugs to eat because the grasses dried up. Population 1 is unaffected because the bugs they eat were still in abundance.

This all has to do with the concept of natural selection. Species with traits that are good for their environment will likely do well unless a change in conditions occurs which makes their traits no longer favorable.

Hope that makes sense!

A population of mice in a meadow is growing in a pattern of logistic growth. Arrange these events in the order in which they occ

Ray Of Light [21]

Answer:

2, 3, 1

Explanation:

For logistic population growth, the initial growth is slow while the population is trying to get acclimatized to the environment but the growth increases exponentially once it is done acclimatizing. The exponential growth continues until the carrying capacity is reached and then starts to fluctuate around the carrying capacity. The carrying capacity signifies the maximum size of the population that the environment can support based on the resources that it has. Hence, the logistic population growth curve forms a S shape.

In summary, the correct order of events is:

The population increase begins to slow
The population increases exponentially
The population fluctuates near carrying capacity

Therefore, the order is 2, 3, 1.
