Ecological Roles in Western Ghats

The video explores the flow of energy and biomass in ecosystems, focusing on trophic levels and food webs. It examines the Western Ghats' food web, highlighting the roles of herbivores, keystone species, and various consumers. The video also discusses decomposers and the nutrient cycle, emphasizing the interconnectedness of organisms and the sustainability of ecosystems.

What is the primary role of photosynthetic plants in an ecosystem?

• To decompose organic matter

• To consume herbivores

• To occupy the top trophic level

• To form the base of the trophic level

What type of forest forms the base of the ecological pyramid in the Western Ghats?

• Deciduous forest

• Shola forest

• Mangrove forest

• Coniferous forest

Which of the following is considered a keystone species in the Western Ghats?

• Gaur

• Malabar parakeet

• Asian elephant

• Nilgiri tar

Which animal is a secondary consumer in the Western Ghats ecosystem?

• Asian elephant

• Malabar parakeet

• Great hornbill

• Nilgiri wood pigeon

What is the role of scavengers in an ecosystem?

• To produce energy from sunlight

• To consume only plant material

• To feed on dead animals

• To occupy the base of the trophic level

Which of the following is a tertiary consumer in the Western Ghats?

• Malabar large spotted civet

• Eagle

• Buffostomaticus

• Nilgiri langur

What is the primary function of detritivores in an ecosystem?

• To consume living plants

• To produce energy from sunlight

• To break down dead organic matter

• To occupy the top trophic level

Which organisms are responsible for breaking down excrement in an ecosystem?

• Omnivores

• Decomposers

• Carnivores

• Herbivores

What role do parasites play in an ecosystem?

• They occupy the base of the trophic level

• They decompose dead matter

• They feed on living organisms

• They produce energy from sunlight

How do decomposers contribute to the nutrient cycle?

• By occupying the top trophic level

• By producing energy from sunlight

• By breaking down organic matter

• By consuming herbivores
