Gneration Geneius Maintaining Biodiversity

How do animals compete within an ecosystem?

• Animals compete for territory and mates only.

• Animals compete for air, food, shelter, water, and space to survive, grow, and reproduce.

• Animals compete primarily for food and water.

• Animals do not compete; they cooperate for survival.

What is a decomposer?

• An organism that breaks down dead matter, recycling nutrients back into the ecosystem.

• A type of plant that produces energy through photosynthesis.

• An animal that hunts and eats other animals for food.

• A microorganism that causes diseases in living organisms.

What is biodiversity?

• Biodiversity is the variety of living organisms in an ecosystem, including the number and diversity of species.

• Biodiversity refers to the total number of ecosystems in a region.

• Biodiversity is the process of evolution of new species over time.

• Biodiversity is the study of the interactions between living organisms and their environment.

What are tide pools?

• Shallow pools of seawater left behind in rock depressions during low tide.

• Deep ocean trenches filled with water.

• Large lakes formed by melting glaciers.

• Artificial ponds created for marine life.

How do plants compete in an ecosystem?

• Plants compete for sunlight, water, space, air, and nutrients from the soil.

• Plants compete primarily for food and shelter from animals.

• Plants compete only for water and sunlight.

• Plants do not compete; they cooperate with each other for resources.

What is a bioindicator, and why is it important?

• A bioindicator is a type of plant that indicates soil quality.

• A bioindicator, like a frog, signals environmental problems in an ecosystem.

• A bioindicator is a chemical used to measure pollution levels.

• A bioindicator is an animal that only lives in clean water.

What is a keystone species?

• A species that is the most abundant in an ecosystem.

• A species that has a critical role in maintaining the balance and health of an ecosystem.

• A species that is at the top of the food chain.

• A species that is only found in a specific habitat.

Why is biodiversity important in an ecosystem?

• Biodiversity helps maintain a balanced and healthy ecosystem where different organisms support one another.

• Biodiversity increases competition among species, leading to extinction.

• Biodiversity reduces the resilience of ecosystems to environmental changes.

• Biodiversity is only important for aesthetic purposes and has no ecological value.

How do protected lands help biodiversity?

• They allow for unrestricted human activities that can harm ecosystems.

• They limit human activities that can harm ecosystems, allowing biodiversity to thrive.

• They promote urban development and industrial growth.

• They increase pollution levels in surrounding areas.

What is an ecosystem?

• A community of only living things in a specific area.

• A collection of non-living things in an environment.

• A community of interacting living (biotic) and non-living (abiotic) things in a particular environment.

• A group of plants that grow together in a forest.
