Many antelope species, including hartebeest, wildebeest, impala, Thompson's gazelle, and others, live on the African plains and eat many of the same food plants. An increase in the population of any of these species leaves less food for the others. This is an example of what type of relationship?

Competition

Explanation:

Competition occurs when many organisms are in search for the same, limiting resource this include food, water,space.

The use of this limited resource by one species decreases availability to the other population especially when there is an increase in population the rate of competition is very high.

Competition reduces the fitness of all the organism and can either be interspecific which is among the same organisms or between different species.

i am positive it is c. condensing but i may be wrong

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
