What is a niche in ecology?

Back

A niche is the role or function of an organism or species within an ecosystem, including its habitat, resource use, and interactions with other organisms.

What does interconnectedness mean in ecology?

Back

Interconnectedness refers to the way in which different organisms and their environments are linked and how changes in one part of an ecosystem can affect others.

Front

What is competition in an ecological context?

Back

Competition occurs when two or more species or individuals vie for the same resources, such as food, space, or mates, which can limit their growth and survival.

Front

Define abiotic factors in an ecosystem.

Back

Abiotic factors are the non-living physical and chemical elements in the environment, such as sunlight, temperature, water, and soil.

Front

What is the significance of feeding at different heights in a tree for bird species?

Back

Feeding at different heights reduces competition for food among bird species, allowing them to coexist more successfully.

Front

Explain the concept of resource partitioning.

Back

Resource partitioning is the process by which different species use different resources or use the same resource in different ways to reduce competition.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with each other and their physical environment.

Front

What are producers in an ecosystem?

Back

Producers are organisms, such as plants and algae, that can make their own food through photosynthesis, forming the base of the food chain.

Front

Define consumers in an ecological context.

Back

Consumers are organisms that cannot produce their own food and must eat other organisms for energy, including herbivores, carnivores, and omnivores.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among organisms in an ecosystem, showing how energy and nutrients flow.
