Answer:
The correct answer is c) logistic
Explanation:
Logistic growth occurs during a population growth when the resources are limiting. During logistic growth sigmoid (S-shaped) growth curve is produced when population size is placed over time.
In logistic growth first the population increases slowly then after some time it increase on the logarithmic phase until it levels off near the maximum carrying capacity due to environmental resistance. Beyond this maximum carrying capacity growth rate does not increase and becomes constant.
This generates an s-shaped curve called a sigmoid curve which shows the logistic growth. So the correct answer is c.
I believe the example of an environmental variation in the above question is, A. Marge dyes her hair blue. Variation represents any difference between cells, individual organisms, or groups of organisms of any species caused by either genetic differences or by the effect of environmental factors. Environmental variation is the ability of an organism to alter its phenotype depending on environmental conditions.
Answer:
Resource conservation
Explanation:
Depresion in term of Resource conservation theory is a mental state where an individual or organism develops motivation to conserve a depleting resources while in search of a new source.
For a depressed organism to reduce energy consumption in order to save for the future, it is exhibiting resource conservation
