Ecological Interactions and Relationships

What is the primary difference between a population and a community?

• A population includes nonliving components, while a community does not.

• A population consists of individuals from different species, while a community is a single species.

• A population is a group of individuals of the same species, while a community includes all living organisms in an area.

• A population refers to all living and nonliving things, while a community refers only to living things.

What is an ecosystem composed of?

• Only living organisms in a specific area.

• A single organism and its immediate surroundings.

• A group of individuals of the same species.

• All living and nonliving things interacting in a specific area.

Which type of organism interaction describes a relationship where both species involved benefit?

• Competition

• Predation

• Mutualism

• Commensalism

What is a key characteristic that distinguishes a parasitoid from a typical parasite?

• Parasitoids only feed on plants, while parasites feed on animals.

• Parasitoids lay eggs inside a host, and their larvae typically kill the host for energy.

• Parasitoids live outside the host, while parasites live inside.

• Parasitoids are much larger than their hosts, unlike parasites.

What defines symbiosis in ecology?

• A short-term interaction between organisms of the same species.

• An interaction where only one species benefits from the relationship.

• A close and long-term interaction between two organisms of different species.

• Any interaction that leads to the extinction of one species.

In the mutualistic relationship between coral and algae, how do they benefit each other?

• Coral provides nutrients, and algae provide shelter.

• Coral provides reef structure and carbon dioxide, while algae provide sugars for energy.

• Algae provide oxygen, and coral provides a place for reproduction.

• Both organisms compete for the same limited resources.

What is the main goal of resource partitioning among different species?

• To increase the overall population size of all species in an ecosystem.

• To eliminate weaker species from a shared habitat.

• To reduce direct competition for shared resources by using them in different ways.

• To encourage species to evolve new resources.

Which type of resource partitioning involves species using the same resource at different times, such as wolves hunting at night and coyotes hunting during the day?

• Spatial partitioning

• Morphological partitioning

• Temporal partitioning

• Competitive exclusion

Resource Partitioning reduces ____________.

• Hunting

• Competition

• Scavenging

• Harmony
