Biodiversity: Ecosystems

What is an ecosystem?

• A type of computer software

• A community of living organisms in conjunction with the nonliving components of their environment, interacting as a system.

• A type of exotic flower

• A new type of exercise equipment

Name three different types of ecosystems.

• Jungle, Glacier, Swamp

• Forest, Desert, Coral reef

• City, Tundra, Ocean

• Mountain, Lake, Volcano

How do living and non-living things interact in an ecosystem?

• Living and non-living things interact through processes such as energy flow, nutrient cycling, and habitat creation.

• Living things interact with non-living things by communicating through sound and visual signals.

• Living and non-living things interact by competing for resources and space.

• Living things interact with non-living things by forming symbiotic relationships.

What is the role of producers in an ecosystem?

• Producers consume energy from other organisms

• Producers only provide shelter for other organisms

• Producers convert sunlight into energy through photosynthesis and form the base of the food chain.

• Producers have no role in the ecosystem

Explain the concept of food chain in an ecosystem.

• The food chain in an ecosystem is a hierarchical series of organisms where each organism is dependent on the next as a source of food.

• The food chain in an ecosystem is a linear sequence of organisms where each organism is independent of the others

• The food chain in an ecosystem is a web of interconnected plants and animals

• Food chain in an ecosystem refers to the process of recycling food waste

What are some factors that can disrupt an ecosystem?

• Only natural disasters

• Only human activity

• All of the above

• None of the above

How does biodiversity contribute to the stability of an ecosystem?

• By reducing the number of species to simplify the ecosystem

• By providing a variety of species that can adapt to changes and help maintain balance.

• By introducing invasive species that disrupt the balance

• By decreasing the genetic diversity within the ecosystem

What are some ways to protect and conserve biodiversity in ecosystems?

• Creating protected areas, promoting sustainable land use practices, controlling invasive species, and reducing pollution

• Increasing pollution levels

• Introducing more invasive species

• Cutting down all trees and plants

Describe the importance of keystone species in an ecosystem.

• Keystone species have no impact on the ecosystem

• Keystone species only benefit themselves and not other species

• Keystone species help regulate the population of other species and maintain the balance of the ecosystem.

• The presence of keystone species has no effect on the population of other species

How does human activity impact biodiversity in ecosystems?

• Biodiversity in ecosystems is not affected by human activity

• Human activity can lead to loss of habitat and extinction of species, impacting biodiversity in ecosystems.

• Human activity has no impact on biodiversity in ecosystems

• Human activity increases biodiversity in ecosystems
