Competition in Ecosystems

What is a food chain?

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

• A diagram that represents the physical structure of an ecosystem.

• A list of all the organisms in a specific habitat.

• A method of classifying different types of food.

What are air, water, and sunlight classified as in an ecosystem?

• Living components

• Nonliving components

• Biotic factors

• Organic materials

What happens to hawks and rabbits if a disease strikes the snake population?

• The population of hawks will increase and the population of rabbits will decrease.

• The population of hawks will remain the same and the population of rabbits will remain the same.

• The population of hawks will decrease. The population of rabbits will increase.

• The population of hawks will decrease and the population of rabbits will decrease.

What role do producers play in an ecosystem?

• They create energy through photosynthesis, forming the base of the food chain.

• They consume other organisms for energy and nutrients.

• They decompose organic matter, returning nutrients to the soil.

• They regulate the population of herbivores in the ecosystem.

What do plants compete for in ecosystems?

• Nutrients, minerals, and soil quality.

• Air, water, space, and sunlight.

• Temperature, humidity, and wind.

• Pests, diseases, and herbivores.

What is the impact of habitat destruction on ecosystems?

• It can lead to loss of species, reduced biodiversity, and disruption of ecological balance.

• It increases the population of certain species.

• It has no significant effect on ecosystems.

• It promotes the growth of invasive species.

What is a limited resource in an ecosystem?

• Something that is needed by organisms and is not infinite in the environment.

• A resource that is abundant and easily accessible to all organisms.

• A type of organism that can survive in extreme conditions.

• A resource that can be created or replenished indefinitely.

What is the significance of biodiversity in ecosystems?

• Biodiversity increases resilience and stability, allowing ecosystems to better withstand changes.

• Biodiversity decreases competition among species, leading to more resources for each species.

• Biodiversity has no significant impact on ecosystem health or stability.

• Biodiversity only benefits certain species, not the ecosystem as a whole.

What do ecosystems depend on organisms to do?

• Interact with each other to maintain stability.

• Compete for resources to thrive.

• Adapt to changing environments for survival.

• Reproduce rapidly to increase population.

What is an example of a nonliving factor in an ecosystem?

• Sunlight

• Trees

• Animals

• Bacteria
