Habitat selection refers to the process by which species choose specific habitats that provide suitable conditions for their survival and reproduction.

Commensalism is a type of interaction where one species benefits from the presence of another without causing any harm or benefit to the latter.

Producers, such as plants, have the highest biomass in a food web because they are the foundation of the food chain and convert sunlight into energy.

Ecological succession refers to the gradual and orderly change in the composition of a community over time, leading to the establishment of a stable and self-sustaining ecosystem.

Competitive exclusion occurs when one species outcompetes another for resources, leading to the decline or elimination of the latter.

Mutualism is a type of interaction where both species benefit from each other's presence, often through cooperation or exchange of resources.

Tertiary consumers, such as top predators, have the lowest biomass in a food chain because they are at the end of the food chain and receive energy from multiple trophic levels below them.

Natural selection is the process by which organisms with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring.

Parasitism is a type of interaction where one species (the parasite) benefits from the presence of another (the host) while causing harm to the host.

Niche partitioning is the process by which species adapt to different environmental conditions and resources within an ecosystem, reducing competition and allowing for coexistence.

Secondary consumers, such as herbivores and omnivores, typically have the greatest diversity of species in a food web because they occupy a wide range of niches and feed on a variety of primary producers and primary consumers.

A climax community is a stable and self-sustaining community of organisms that has reached a state of equilibrium with its environment.

Competition is a type of interaction where both species are negatively affected by each other's presence, often due to the limited availability of resources.

Population dynamics refers to the study of how populations of organisms change over time, including factors such as birth rates, death rates, and migration.
