1. What is an ecosystem?

> An ecosystem is a community of living organisms (plants, animals, microorganisms) interacting with each other and their non-living environment (such as soil, water, air, and sunlight) in a specific area.

Explanation: An ecosystem includes all the biotic (living) and abiotic (non-living) components that function together as a unit. For example, in the image, the fish, deer, plants, insects, water, sun, and soil all interact — this whole system is an ecosystem.

2. Name three (3) types of ecosystem found in The Bahamas.

> 1. Coral Reef Ecosystem
> 2. Mangrove Forest Ecosystem
> 3. Tropical Rainforest or Dry Forest Ecosystem

Explanation: The Bahamas is an archipelago known for its rich biodiversity. Its major ecosystems include:
- Coral Reefs — Found underwater around the islands, supporting fish, corals, and other marine life.
- Mangrove Forests — Coastal wetlands that protect shorelines and serve as nurseries for many sea creatures.
- Tropical Forests — Including dry forests and pine woodlands found on the islands, home to native birds, reptiles, and plants.

*(Note: Other acceptable answers might include “seagrass beds” or “beach/dune ecosystems.”)*

3. Name two (2) living things found in an ecosystem.

> 1. Deer
> 2. Fish

*(Other possible answers from the image: bird, dragonfly, frog, plant, turtle, insect, etc.)*

Explanation: Living things (also called *biotic factors*) are organisms that grow, reproduce, use energy, and respond to their environment. In the picture, the deer and fish are clearly living animals.

4. Name two (2) non-living things found in an ecosystem.

> 1. Water
> 2. Sunlight

*(Other possible answers from the image: soil, rocks, log, air, temperature, etc.)*

Explanation: Non-living things (also called *abiotic factors*) are physical and chemical elements in the environment that affect living organisms. In the image, the pond water and the sun are essential non-living components that support life in the ecosystem.

✔ Completed Worksheet Summary:

1. Ecosystem definition — Community of living + non-living things interacting in an area.
2. Bahamas ecosystems — Coral reef, mangrove forest, tropical forest.
3. Living things — Deer, fish.
4. Non-living things — Water, sunlight.

This worksheet helps students understand how ecosystems work by observing real-world examples and distinguishing between biotic and abiotic components.
