Ecosystem Review Sheet
Using the diagram, answer the following questions:
1. What is the herbivore in this food chain? Grasshopper
2. What is the producer in this food chain? Flower
3. What would happen to this food chain if the flowers were covered in fertilizer
It would poison the grasshopper, frog, and snake
4. Using this food chain, draw an energy pyramid.
Using the diagram above, answer the following questions:
5. What is the one herbivore in this food web? Squirrel
6. What is the top consumer in this food web? Bear
7. Besides the bear, what is the other omnivore in the food web? Raccoon
8. What would happen to the food web if the raccoon was removed from the web?
There would be more fish and plants because the raccoon wouldn’t eat them, but the
bear would have to eat more food because one of its food sources would be gone

Use the Food Pyramid for #17 and #18:
12. Which one of these organisms is the most plentiful?
Algae
13. What is the primary consumer?
Copepods
9. Which one of these organisms would receive all of their
nutrients from abiotic sources? Grass
10. Which one of these organisms recycles materials? Fungus
11. Which one of these organisms receives its energy from a
producer? Grasshopper
14. What is the difference between a food chain and food web?
Food webs show multiple connections between the different producers and consumers
15. What type of energy is passed from a producer to a consumer?
Chemical Energy
16. List and describe the 7 plant adaptations related to water:
1. Flexible Roots- allow roots to move with water and not break
2. Sun Absorption- Chlorophyll only on top of leaves
3. No Root- some plants can absorb water through their leaves and stems
4. Spines- small leaves to stop H20 evaporation, protect plants from animals
5. Water Storage- water stored in stem
6. Waxy Stem- stops water evaporation
7. Drip tip & Waxy leaves- allows water to run off so fungi doesn’t grow
Define the following terms and write an example for each term on a separate paper
17. Biotic Living organisms- bird
18. Abiotic nonliving factors-sun
19. Population All the organisms in an ecosystem that belong to the same species
20. Consumer Organisms that cannot make their own food
21. Prey An organism that is hunted and killed for food
22. Producer An organism that can make its own food

23. Ecosystem All of the organisms living in an area and the nonliving factors of their environment
24. Habitat The place an organism lives
25. Herbivore An animal that only eats producers
26. Xylem A pipe in a plant that carries water to all parts of the plant
27. Phloem A pipe in a plant that carries food to all parts of the plant
28. Turgor Pressure The outward force of the central vacuole on the inside of the cell wall
29. Phototropism the direction an organism grows in response to light
30. Hydrotropism the direction an organism grows in response to water
31. Gravitropism the direction an organism grows in response to gravity
32. Thigmotropism the direction an organism grows in response to touch
33. Chlorophyll the pigment in chloroplast that absorbs light energy
34. Chloroplast The organelle where photosynthesis takes place
35. Write the formula for photosynthesis and explain the process in complete sentences.
Photosynthesis is the process that converts light energy into chemical energy that takes place
in the chloroplast organelle of plants. Sunlight is absorbed by chlorophyll in the plants leaves.
The plants also take in carbon dioxide from humans and animals, and soak up water from their
roots. Sunlight, carbon dioxide, and water combined in a plant will produce glucose which is
sugar/food for the plant, and release oxygen for animals and humans to consume.
