Mutualism Commensalism Parasitic

Give an example of commensalism.

• Barnacles attaching to a whale; barnacles benefit by getting a place to live, while the whale is not affected.

• A bird building a nest in a tree; the tree is not harmed but the bird benefits.

• A lion hunting a zebra; the lion benefits by getting food while the zebra is harmed.

• A bee pollinating a flower; the bee benefits from nectar while the flower is not affected.

What is parasitism?

• A type of symbiotic relationship where both organisms benefit.

• A type of symbiotic relationship where one organism benefits at the expense of the other, which is harmed.

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

• A type of relationship where organisms live independently without affecting each other.

What is symbiosis?

• A type of competition between species for resources.

• A close long-term association between two or more species, which can be mutualistic, commensal, or parasitic.

• A method of reproduction in plants.

• A process of evolution in isolated species.

How many types of symbiosis are there?

• Two types: mutualism and commensalism

• Four types: mutualism, commensalism, parasitism, and amensalism

• Three types: mutualism, commensalism, and parasitism

• One type: symbiosis

What is an ecosystem?

• A community of living organisms interacting with their environment.

• A type of biome with specific climate conditions.

• A collection of non-living things in a specific area.

• A group of organisms that cannot interact with each other.

What is a food chain?

• A linear sequence of organisms through which nutrients and energy pass as one organism eats another.

• A diagram that shows the different types of food consumed by animals.

• A complex network of food webs that includes all organisms in an ecosystem.

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

What is the role of a predator in an ecosystem?

• A predator hunts and eats other organisms (prey), helping to control population sizes.

• A predator primarily feeds on plants and decomposes organic matter.

• A predator provides shelter and protection to other species in the ecosystem.

• A predator is responsible for pollinating plants and aiding in reproduction.

What is the role of a producer in an ecosystem?

• Producers, like plants, create their own food through photosynthesis and provide energy for other organisms.

• Producers are organisms that consume other organisms for energy.

• Producers are responsible for decomposing organic matter in the ecosystem.

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

What is competition in ecology?

• Occurs when two or more organisms use the same resource, leading to a struggle for survival.

• A process where organisms adapt to their environment over time.

• The interaction between different species in a habitat.

• A method of reproduction among various species.
