1. Analyse and differentiate between the organisms given below as per their eating habits.
- Horse: Herbivore – It feeds on plants, such as grass, hay, and grains. It has a digestive system adapted to break down cellulose found in plant cell walls.
- Eagle: Carnivore – It feeds on other animals, such as small mammals, birds, and fish. It has sharp talons and a hooked beak to capture and tear its prey.
2. Observe the image, read the lines and answer the questions that follow:
Q1. What do you understand by the term 'food chain'?
Ans: A food chain is a linear sequence of organisms through which energy is transferred in an ecosystem. It starts with a producer (like plants) that makes its own food, followed by consumers (herbivores, carnivores, omnivores) that eat other organisms. Each level in the food chain is called a trophic level.
Q2. Identify and describe the process conducted by the producers to gain energy.
Ans: Producers, such as plants, gain energy through the process of photosynthesis. In this process, they use sunlight, carbon dioxide from the air, and water from the soil to produce glucose (a form of sugar) and oxygen. The energy from sunlight is converted into chemical energy stored in glucose, which the plant uses for growth and other life processes.
