Ecosystem - Worksheet | Easel Activity & Printable PDF by Science ... - Free Printable

I can see Question 3 clearly now. It asks: "From the following food chain which organism can be described as a producer?" with a diagram showing:
Grass → Grasshopper → Frog → Snake

The options are:
a) Grasshopper
b) Frog
c) Snake
d) Grass

In ecology, a producer is an organism that produces its own food, typically through photosynthesis. In this food chain, grass is at the beginning and is a plant that performs photosynthesis to create its own energy. The grasshopper eats the grass, the frog eats the grasshopper, and the snake eats the frog.

Therefore, the producer in this food chain is grass (option d).

Let me now review all the answers I've found for each question:

Question 1: Fill in the blanks
1. Ecosystem
2. Habitat
3. Herbivores
4. Carnivores
5. Food chain
6. Food web

Question 2: Which is an abiotic factor?
Answer: b) Sunlight

Question 3: Which organism is a producer?
Answer: d) Grass

Based on my analysis of the ecosystem diagram and the questions, I have solved all parts of the worksheet.

The complete solution to the ecology worksheet is:

Question 1: Fill in the blanks
1. Ecosystem
2. Habitat
3. Herbivores
4. Carnivores
5. Food chain
6. Food web

Question 2: Which of the following is abiotic factor in an ecosystem?
Answer: b) Sunlight

Question 3: From the following food chain which organism can be described as a producer?
Answer: d) Grass

Additional observation from the diagram:
For the question "What does the eagle eat in this ecosystem?" (which appears below the main diagram), based on the arrows showing energy flow, the eagle eats lizard, rabbit, rat, and snake. Therefore, the correct answer would be c) lizard, rabbit, rat and snake.
