Ecosystem Relationships and Functions

The video tutorial from Guru Ipa channel discusses the interaction of living organisms with their environment. It defines the environment, its biotic and abiotic components, and the concept of habitat. The video explains the interactions within ecosystems, including food chains, webs, and symbiosis types: mutualism, commensalism, and parasitism. It also covers the roles of autotrophs and heterotrophs, and the impact of human activities on the environment. The video concludes with a call to action for viewers to engage with the channel.

What are the two main components of the environment?

• Organic and Inorganic

• Natural and Artificial

• Physical and Chemical

• Biotic and Abiotic

Which of the following best describes an ecosystem?

• A collection of abiotic factors only

• A community of organisms interacting with each other and their environment

• A group of similar species living together

• A single organism living in isolation

What is the term for a relationship where both species benefit?

• Mutualism

• Commensalism

• Parasitism

• Predation

Which example illustrates commensalism?

• Bee and flower

• Fungus and tree roots

• Leech and human

• Orchid and mango tree

Which of the following is an example of parasitism?

• Clownfish and anemone

• Leech and human

• Orchid and mango tree

• Bee and flower

What type of organism can produce its own food?

• Carnivore

• Omnivore

• Autotroph

• Heterotroph

Which of the following is a characteristic of heterotrophs?

• They are always carnivores

• They rely on other organisms for food

• They produce their own food

• They are always herbivores

What is the role of autotrophs in an ecosystem?

• They decompose organic matter

• They produce energy-rich compounds

• They consume other organisms

• They provide shelter for animals

How do human activities affect the environment?

• They only affect abiotic components

• They can degrade environmental quality

• They have no impact on the environment

• They always improve environmental quality

What is the result of environmental degradation?

• Reduced functionality of the environment

• Increased biodiversity

• Enhanced natural resources

• Improved ecosystem services
