Ecology and Food Chain Concepts

The video tutorial explores how living things depend on their environment to meet basic needs. It covers various environments like beach, desert, forest, and arctic, and explains how organisms such as sharks, polar bears, cacti, and orangutans adapt to these environments. The tutorial also discusses biotic and abiotic factors, interdependence, and food chains, providing examples and interactive exercises to reinforce learning.

What is the primary source of air for a shark?

• The desert

• The forest

• The beach

• The ocean water

Why can't a polar bear survive in the desert?

• Its body is not adapted to the heat

• It cannot find enough food

• It prefers dry environments

• It needs a lot of sunlight

Which part of the environment does a cactus store water in?

• Its flowers

• Its seeds

• Its roots, stem, and leaves

• Its thorns

What are biotic factors?

• Non-living things like sunlight and minerals

• Chemical elements like oxygen

• Living things like plants and animals

• Physical conditions like temperature

Which of the following is an example of an abiotic factor?

• Soil

• Protists

• Fungus

• Bacteria

What is ecology?

• The study of interactions between organisms and their environment

• The study of plants

• The study of climate change

• The study of animal behavior

In a food chain, what role do producers play?

• They decompose organic matter

• They consume other organisms

• They make their own food from non-living resources

• They are the final consumers

Which organism is a primary consumer in the given food chain example?

• Grasshopper

• Frog

• Snake

• Grass

What is the role of decomposers in a food chain?

• They produce energy from sunlight

• They consume primary consumers

• They break down dead organisms

• They are the top predators

Which of the following is a producer?

• Fungi

• Mouse

• Fox

• Grass
