Here are the answers to the questions on your worksheet.
Study the food web and answer the following questions:
Q1. What is a food web?
A food web is a diagram that shows how different plants and animals in an ecosystem are connected by what they eat. It is made up of many food chains linked together, showing that most animals have more than one source of food.
Q2. What would happen if the snake population decreases?
If the snake population decreases, the animals that snakes eat (like frogs, birds, and mice) will likely increase in number because fewer of them are being eaten. At the same time, the animals that eat snakes (like hawks) might decrease in number or have to eat more of their other prey (like rabbits or foxes) to survive.
Q3. When do we consider the ecosystem to be in equilibrium?
An ecosystem is in equilibrium when the populations of all the plants and animals remain relatively stable over time. This happens when there is enough food and resources for everyone, and no single species grows too large or dies out completely.
Q4. What happens to energy as we move up from one step to another in a chain or web?
As energy moves up from one step to the next (for example, from grass to a rabbit), some of it is used by the animal for living activities like moving and staying warm, and some is lost as heat. This means less energy is available for the animal at the next step.

Study the food chain and answer the following questions:
Q1. What is a food chain?
A food chain is a simple line that shows the order of who eats whom in nature. It starts with a producer (usually a plant) and ends with a top predator, showing the flow of energy from one living thing to another.
Q2. Name the producer in the food chain.
Grass
Final Answer:
Food Web Section:
Q1: A food web is a network of interconnected food chains showing feeding relationships in an ecosystem.
Q2: Prey populations (frogs, birds, mice) would increase, while predator populations (hawks) might decrease or shift diets.
Q3: When populations of organisms remain stable and balanced over time.
Q4: Energy decreases; much of it is used for life processes or lost as heat.
Food Chain Section:
Q1: A linear sequence showing how energy moves from one organism to another through eating.
Q2: Grass
