Resource partitioning within an ecosystem:A increases competition;
A
for example, species of wading shorebirds have different leglengths.
B
decreases competition; for example, different forest birds may feed at varying heights above the ground.
C
increases competition because different organisms cannot feed on the same food sources at the same time.
D
decreases competition because most animals feed during the day and sleep at night.
Explanation: 

Detailed explanation-1: -The anole lizards found on the island of Puerto Rico are a good example of resource partitioning. In this group, natural selection has led to the evolution of different species that make use of different resources.

Detailed explanation-2: -Similar species commonly use limiting resources in different ways. Such resource partitioning helps to explain how seemingly similar species can coexist in the same ecological community without one pushing the others to extinction through competition.

Detailed explanation-3: -The Anole lizards compete for the same food, i.e., insects. Some lizards live on the forest floor while some may live higher up in their habitat in trees. This habitat partitioning based on their physical location helps in their coexistence more effectively.

Detailed explanation-4: -There are two kinds of resource partitioning; it can either be a form of habitat partitioning or food partitioning.
