Answer: White pulp of the spleen
Explanation:
The white pulp of the spleen is that region found in the spleen which appears white in color.
It appears whiter than the surrounding red pulp on the gross section which consitutes to about 25% of the whole splenic tissue.
This area has antigen presenting cells and dendritic cells and macrophages. Some of the cells there are known as metallophillic mcrophages which helps in keeping the body free from diseases.

Based on the data provided, we can conclude that the graph in question corresponds to the K-selected theory in regards to the human species.
When considering the data of certain species and grouping them into categories such as extinct, endangered, or K/r-selected we take into account factors such as:
- Population size
- Behavior
- Carrying capacity
- Reproduction rates
and so on, then classify each species accordingly.
Species that are Extinct are no longer on the earth. This classification refers to species of the past and does not include humans as of yet. The endangered category is reserved for species whose population sizes are <u>at a critical low and are near </u><u>extinction</u>, which is also not the case for humans.
The K-selected and r-selected theories consider reproduction rates and carrying capacity as well when grouping species. Species that produce few offspring at a time are often found in this group. This category also refers to species whose offspring have a high chance of survival into maturity and whose population size is near the limit of the environment. All of this follows the data given and is the classification for the human species.

Grasses are the producers. Gazelles, warthogs, and wildebeests are primary consumers. Lions and cheetahs would be the secondary consumers.
Fur has a thick layer of protection to help protect..say a bear in this case. A polar bear's fur is helpful in the cold, to prevent the bear from freezing to death.
But since a polar bear eats fish and things that it's used to in Antarctica, it probably won't adapt as easily.
