Ecology Concepts and Interactions

The video tutorial explains the interactions among living and non-living things in an ecosystem, focusing on biotic and abiotic factors. It introduces ecology and ecologists, and details various interactions such as symbiosis, predation, and competition. Symbiosis includes mutualism, commensalism, and parasitism, while predation involves predator-prey relationships. Competition is discussed in terms of resource scarcity among organisms.

What is the term for the interaction of living and non-living things in an environment?

• Ecosystem

• Habitat

• Biosphere

• Community

Who are the scientists that study the interactions among organisms and their environment?

• Zoologists

• Biologists

• Geologists

• Ecologists

What is a group of organisms that belong to the same species called?

• Community

• Habitat

• Population

• Ecosystem

In a biotic community, how do different species interact with one another?

• Through isolation

• Through symbiosis, predation, or competition

• Through migration

• Through evolution

Which type of symbiotic relationship benefits both organisms involved?

• Predation

• Commensalism

• Mutualism

• Parasitism

In commensalism, how is the second organism affected?

• It is harmed

• It is benefited

• It is neither harmed nor benefited

• It is killed

What is the term for a parasite that lives inside the host's body?

• Predator

• Symbiont

• Endoparasite

• Ectoparasite

In a predator-prey relationship, what role does the prey play?

• It hunts the predator

• It competes with the predator

• It benefits the predator without harm

• It is eaten by the predator

What is the main cause of competition among organisms in a biotic community?

• Symbiosis

• Abundance of resources

• Limited resources

• Isolation

What happens to plants that lose in competition for nutrients?

• They might die or experience stunted growth

• They become predators

• They grow faster

• They thrive
