Question

natural selection and moths - graphing and... / natural selction graph moth... saved recall that there are four parts of natural selection to take place. a) below is a series of pictures representing changes in a population of cacti. pictures 1 and 2 show what happened when a deer came to eat, picture 3 shows the cacti a few weeks later (notice the flowers on the right - hand cactus), and picture 4 shows the situation a few months later. 1) what is overproduction? overproduction is when an organism or species produces more offspring than can possibly survive in its environment due to limited resources like food, water, and shelter. 2) genetic variation within the population: in picture 1, what is the main difference between the cactus on the left and the cactus on the right? 3) struggle to survive: why would a deer be more likely to eat the cactus on the left than the cactus on the right in picture 1? 4) differential successful reproduction (fitness): what effect does the deers behavior have on the survival and reproduction of these two types of cactus?

Explanation:

1. Over - production is defined as an organism or species producing more offspring than can survive due to limited resources.
2. In picture 1, the main difference between the cactus on the left and right is likely in their physical characteristics such as size, shape, or number of spines which represent genetic variation.
3. A deer may be more likely to eat the cactus on the left in picture 1 because it may have fewer spines or be more accessible, making it an easier food source in the struggle for the deer to obtain nutrition.
4. The deer's behavior affects the survival and reproduction of the two types of cacti. The cactus more preferred by the deer has a lower chance of survival and reproduction, while the less - preferred cactus has a higher chance to survive and reproduce, leading to differential successful reproduction.

Answer:

1. Overproduction is when an organism or species produces more offspring than can possibly survive in its environment due to limited resources like food, water, and shelter.
2. The main difference could be in physical traits such as number of spines, size, etc. representing genetic variation.
3. It may have fewer spines or be more accessible.
4. The preferred cactus has lower survival and reproduction chances, while the less - preferred one has higher chances.
