Interactions in Ecosystems

What is competition in an ecosystem?

• Competition occurs when two or more organisms vie for the same resources (food, space, light) in an ecosystem.

• Competition is when organisms help each other to survive and thrive in an ecosystem.

• Competition refers to the process of organisms adapting to their environment over time.

• Competition is the relationship between predators and their prey in an ecosystem.

What is ecological succession?

• The process by which ecosystems change and develop over time, often following a disturbance, leading to a new community structure.

• A method of planting trees in urban areas to improve air quality.

• The phenomenon of species extinction due to habitat loss.

• A technique used in agriculture to increase crop yield.

What is parasitism?

• A relationship where both organisms benefit from each other.

• A relationship where one organism benefits at the expense of another, often harming it.

• A relationship where organisms compete for the same resources.

• A relationship where one organism lives in harmony with another without affecting it.

What is commensalism?

• A type of symbiotic relationship where one organism benefits and the other is neither helped nor harmed.

• A relationship where both organisms benefit from each other.

• A relationship where one organism is harmed while the other benefits.

• A type of relationship where organisms compete for the same resources.

What is a decomposer?

• Organisms that produce energy through photosynthesis.

• Organisms that break down dead or decaying organic material, returning nutrients to the soil.

• Organisms that consume primary producers for energy.

• Organisms that live in symbiosis with plants to enhance nutrient uptake.

What is a food web?

• A simple chain of organisms that eat one another.

• A complex network of interconnected food chains in an ecosystem, illustrating how different organisms are related through feeding relationships.

• A diagram that shows the energy flow in a single species.

• A list of all the plants and animals in a specific area.

What is mutualism?

• A type of relationship where one organism benefits at the expense of another.

• A type of symbiotic relationship where both organisms benefit from the interaction.

• A relationship where organisms compete for the same resources.

• A type of relationship that occurs only in aquatic environments.

What is biodiversity?

• Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species and their interactions.

• Biodiversity is the total number of organisms in a specific area, regardless of species.

• Biodiversity only includes the number of plants in an ecosystem.

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

What is predation?

• A biological interaction where one organism hunts and kills another for food.

• A symbiotic relationship where both organisms benefit.

• A process of photosynthesis in plants.

• A method of reproduction in animals.

What is an invasive species?

• A native organism that thrives in its natural habitat.

• A non-native organism that spreads widely in a new habitat, often causing harm to native species and ecosystems.

• An organism that is beneficial to the local ecosystem.

• A species that is endangered and protected by law.
