Question

Visit an ecosystem nearby, List the biotic and abiotic factors in it. Show with pictures or sketches, how they are dependant on each other.

Answer 1

To explore an ecosystem nearby, follow these steps to identify the biotic and abiotic factors, and illustrate their interdependence.

Step 1: Visit a Nearby Ecosystem

Choose an accessible ecosystem such as:

• A garden or park (terrestrial ecosystem),
• A pond or lake (aquatic ecosystem),
• A forest or grassland (natural habitat).

Step 2: List Biotic and Abiotic Factors

• Biotic Factors
• Abiotic Factors

Step 3: Show Interdependence

• Sunlight and Plants: Sketch how sunlight enables plants to perform photosynthesis, producing oxygen and food for animals.

• Water and Aquatic Life: Show how fish depend on oxygen dissolved in water, while aquatic plants rely on sunlight and nutrients in the water.

• Soil and Decomposers: Illustrate how decomposers break down organic matter in the soil, recycling nutrients for plants.

• Food Chain: Draw a simple food chain - Grass (Producer) → Grasshopper (Primary Consumer) → Frog (Secondary Consumer) → Snake (Tertiary Consumer) Grass  (Producer)

Step 4: Create a Diagram

Draw or use software to design a diagram like this:

1. Circle Sunlight: Indicate its role in photosynthesis.
2. Draw Plants Growing in Soil: Label water, air, and temperature influencing growth.
3. Show Food Chain Connections: Link producers, consumers, and decomposers.
4. Arrows for Dependency: Use arrows to indicate the flow of energy and matter.
