Competition and Predation

What is a habitat?

• A habitat is a type of food that animals eat.

• A habitat is a place where animals and plants naturally live.

• A habitat is a type of animal species.

• A habitat is a method of reproduction in plants.

What is the impact of invasive species on native ecosystems?

• Invasive species have no effect on native ecosystems.

• Invasive species can enhance the growth of native species.

• Invasive species can disrupt local ecosystems by outcompeting native species for resources, altering habitats, and introducing diseases.

• Invasive species only affect the physical appearance of ecosystems.

What role does a tiger play in its ecosystem?

• A herbivore

• A scavenger

• A predator

• A decomposer

How do predators affect prey populations?

• Predators help regulate prey populations, preventing overpopulation and promoting a balance in the ecosystem.

• Predators increase the number of prey by providing them with more resources.

• Predators have no significant impact on prey populations.

• Predators only affect the size of the prey population during certain seasons.

Define predation.

• Predation is a symbiotic relationship where both organisms benefit.

• Predation is the interaction where one organism (the predator) kills and eats another organism (the prey).

• Predation is the process of organisms competing for the same resources.

• Predation is a form of mutualism where two species help each other survive.

What role does a shark play in its ecosystem?

• A scavenger

• A herbivore

• A predator

• A decomposer

What is resource partitioning?

• A process where species compete for the same resources

• The way species use the environment differently to coexist

• A method of resource depletion among species

• A strategy for increasing competition among species

What is the significance of biodiversity in ecosystems?

• Biodiversity increases the number of species in an ecosystem, leading to more competition.

• Biodiversity contributes to ecosystem resilience, stability, and productivity, allowing ecosystems to better withstand environmental changes.

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

• Biodiversity only benefits certain species and does not affect the overall ecosystem.

What is a niche in an ecosystem?

• A type of organism that lives in a specific habitat.

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

• A measure of biodiversity in a given area.

• The physical space an organism occupies in an ecosystem.

What is competition in an ecological context?

• Competition occurs when two or more species or individuals vie for the same resources in an ecosystem, such as food, space, or light.

• Competition is the process by which species evolve to adapt to their environment.

• Competition refers to the mutualistic relationships between different species in an ecosystem.

• Competition is the phenomenon where species cooperate to share resources.
