Activation energy is required to start a chemical reaction. Activation energy is the energy needed to allow the reactant to react. Activation energy is measured in Joules (J).
How diseases happens to spread in communities is the direct contact of bacteria, viruses or other germs from one person to another. This can happen when an individual with bacterium or virus touches, kisses, or coughs on someone who isn’t infected.
Answer:
Because of niche partitioning or differentiation.
Explanation:
Competition is a common ecological and evolutive process in nature. Competition might be intra- or interspecific. Competition between different species in a community or ecosystem might be due to the same resource use, or the same territory, shelter, etcetera. When a resource is useful for two or more species and limited, they compete to gain it.
The <u>principle of competitive exclusion</u> states that different species with the same requirements sharing the niche can not coexist indefinitely based on the same limited resource. <u>When two competing species coexist, this is because of niche partitioning or niche differentiation.</u>
Differentiation of effective niche is closely related to character displacement. Resource partitioning and differentiation allow both species to coexist more effectively.
In the exposed example, swallows and bats feed on insects and breed in similar habitats. However, swallows feed during the day, while bats feed during the night. Feeding at different times is an example of niche differentiation. In this way, both species can inhabit the same area and feed on the same source of food, but avoid competition.
