Ecology Vocabulary Terms

What is a niche?

• A type of plant that grows in wet environments.

• The role or function of an organism within its ecosystem, including its habitat, resource use, and interactions with other organisms.

• A geographical area where a specific species is found.

• A method of reproduction in animals.

What is the role of producers in an ecosystem?

• Producers convert sunlight into energy through photosynthesis, forming the base of the food chain.

• Producers are organisms that consume other organisms for energy.

• Producers are responsible for decomposing organic matter in the ecosystem.

• Producers are organisms that compete for resources with consumers.

Why is interdependence important for ecosystems?

• It allows species to compete for resources more effectively.

• It ensures that species can survive and thrive through their relationships with one another.

• It reduces the number of species in an ecosystem.

• It increases the likelihood of natural disasters.

What is the difference between a population and a community?

• A population is a group of individuals of different species living in a specific area, while a community includes only one species in that area.

• A population is a group of individuals of the same species living in a specific area, while a community includes all the different species interacting in that area.

• A population refers to the total number of organisms in an ecosystem, while a community refers to the physical environment.

• A population is a group of individuals living in different areas, while a community is a group of individuals living in the same area.

What is interdependence in ecology?

• Interdependence refers to the survival of species being dependent on other living organisms and nonliving components in their environment.

• Interdependence is the ability of a species to survive without any interaction with other species.

• Interdependence means that all species in an ecosystem are completely independent of each other.

• Interdependence refers to the competition between species for limited resources.

What is a habitat?

• A habitat is a type of organism.

• A habitat is a place where organisms live, including both biotic and abiotic factors.

• A habitat is a method of reproduction.

• A habitat is a food source for animals.

How do biotic and abiotic factors interact in an ecosystem?

• Biotic factors are independent of abiotic factors and do not require them for survival.

• Biotic factors depend on abiotic factors for survival; for example, plants (biotic) need sunlight and water (abiotic) to grow.

• Abiotic factors are the primary determinants of ecosystem health, with biotic factors playing a minor role.

• Biotic factors can thrive without any abiotic factors present in the ecosystem.

What are consumers in an ecosystem?

• Organisms that produce energy through photosynthesis

• Organisms that obtain energy by eating other organisms, including herbivores, carnivores, and omnivores.

• Organisms that decompose dead matter

• Organisms that live in symbiosis with producers

• Water

• Trees

• Animals

• Bacteria

Define decomposers and their role in an ecosystem.

• Decomposers are organisms that produce energy through photosynthesis.

• Decomposers, like fungi and bacteria, break down dead organic matter, recycling nutrients back into the ecosystem.

• Decomposers are primary consumers that feed on plants and herbivores.

• Decomposers are large animals that hunt and kill other animals for food.
