What is competition in an ecosystem?

• A process where organisms cooperate for resources

• A situation where organisms fight for dominance

• Competition occurs when two or more organisms vie for the same resource, such as food or shelter.

• A method of reproduction among species.

What is a community in an ecosystem?

• A community is a group of different species living together in the same area.

• A community is a single species that dominates an area.

• A community is a collection of abiotic factors in an environment.

• A community is a group of organisms that do not interact with each other.

What is ecological succession?

• The process of change in the species structure of an ecological community over time.

• A method of measuring biodiversity in an ecosystem.

• The introduction of non-native species into an ecosystem.

• The seasonal migration of animals in response to climate changes.

What is a food web?

• A food web is a simple chain of food sources.

• A food web is a complex network of interconnected food chains in an ecosystem.

• A food web is a type of food chain that includes only plants.

• A food web is a diagram that shows the energy flow in a single species.

• The total number of organisms in a given area.

What is the significance of biodiversity in an ecosystem?

What is a food chain?

• A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

• A food chain is a circular pattern of energy flow in an ecosystem.

• A food chain is a complex network of food webs that includes all organisms in an area.

• A food chain is a list of all the plants and animals in a specific habitat.
