Q1. A food web is a group of connected food chains that show how energy moves between animals and plants in an ecosystem.
Q2. If the snake population decreases, the animals it eats (like mice and frogs) might increase, and the animals that eat snakes (like hawks and owls) might have less food and decrease too.
Q3. We consider the ecosystem to be in equilibrium when all the populations of animals and plants stay balanced and stable over time.
Q4. As we move up from one step to another in a chain or web, energy decreases because some is lost as heat or used for life processes.
Q5. A food chain is a simple path that shows who eats whom, starting from a plant or sun and going up to a top predator.
Q6. The producer in the food chain is grass.
