B is correct, Organisms in the same group have similar characteristics
Rinderpest disease is caused by a virus that affects hoofed animals, including cattle and wildebeest. In the 1950s, a cattle vaccination program was implemented to eradicate the disease in the Serengeti, and this led to dramatic changes in the populations of wildebeest and other species. The figure shows the number of wildebeest in the Serengeti ecosystem (shaded circles, left y-axis) and the prevalence (i.e., percentage) of individuals infected by rinderpest disease (unshaded squares and triangles, right y-axis) from 1958 to 2003.

>examples of mutualism
~Hummingbird Hawkmoth drinking from Dianthus. Pollination is a classic example of mutualism

Producers are organisms that capture sunlight from the sun to make organic food. Consumers are animals and get food by consuming other organisms. Decomposers break down all dead organisms from a soil bacterium part of the food cycle. Detritivore feed on organic matter. Producers get their food from the sun. And compete with all organisms above them on the food pyramid. A food chain is a cycle pathway of life, relationships among organisms is a mutualism that results in energy. Most energy is lost as metabolic heat, the total heat, and energy wast. Meaning that each level only receives 10% of the energy in the level
