Ecosystems

What is the impact of invasive species on ecosystems?

• Invasive species can enhance biodiversity by introducing new species.

• Invasive species can disrupt local ecosystems, outcompeting native species and altering habitats.

• Invasive species have no significant impact on ecosystems.

• Invasive species only affect the species they directly interact with.

What is a community in the context of ecosystems?

• A community is a group of individuals of the same species living in a specific area.

• A community is all the populations in a certain area at the same time.

• A community is the physical environment where organisms live.

• A community is a collection of different ecosystems in a region.

What is an example of a scavenger in an ecosystem?

• A lion

• A vulture

• A rabbit

• A deer

What is the concept of carrying capacity in an ecosystem?

• The total biomass of all species in an ecosystem.

• The maximum number of individuals of a species that an environment can sustainably support.

• The rate at which energy is transferred through an ecosystem.

• The variety of different species within a given area.

What do we call a consumer that only eats other animals?

• Herbivore

• Carnivore

• Omnivore

• Detritivore

What is the significance of decomposers in an ecosystem?

• Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.

• Decomposers produce energy through photosynthesis.

• Decomposers compete with producers for sunlight.

• Decomposers are the primary consumers in the food chain.

What is a food chain?

• A circular process of energy transfer among organisms.

• A linear sequence that shows how energy and nutrients flow from one organism to another.

• A method of food preservation used in agriculture.

• A type of ecosystem that includes only plants.

What is biodiversity?

• Biodiversity refers to the variety of life in a particular habitat or ecosystem.

• Biodiversity is the number of species that can be found in a single organism.

• Biodiversity is the study of how organisms interact with each other.

• Biodiversity refers to the total number of organisms in a specific area.

What is a food web?

• A simple chain of food sources in an ecosystem.

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

• A type of food chain that only includes plants.

• A diagram showing the energy flow in a single species.

What is the role of producers in an ecosystem?

• Producers are organisms that create their own food through photosynthesis, forming the base of the food chain.

• Producers are organisms that consume other organisms for energy.

• Producers are organisms that decompose dead matter and recycle nutrients.

• Producers are organisms that rely on external sources for their food.
