Ecosystems & Environment

How living things interact with each other and their surroundings

Grade 10 Life Sciences

In this section, learners study ecology. You need to know how living things depend on each other, how energy moves through ecosystems, and how nutrients are recycled in nature.

1

Biosphere

The layer of Earth that supports life - from the deepest oceans to the highest mountains.

2

Biomes of South Africa

Explore our country's unique biomes - from Fynbos to Savanna, Grassland to Forest.

Ecosystems

Learn how communities of plants and animals interact with their environment.

Communities Habitats Interactions
4

Abiotic Factors

The non-living things that affect life - sunlight, water, temperature, and soil.

5

Biotic Factors

The living parts of ecosystems - producers, consumers, decomposers, and their interactions.

Producers Consumers Decomposers
6

Energy Flow

How energy from the sun moves through food chains, food webs, and trophic levels.

Ecotourism

How responsible tourism can help protect nature and support local communities.

How to Study Ecosystems Effectively

Start with the Basics

Begin with the Biosphere and work your way through the topics in order - each one builds on the previous.

Draw Diagrams

Sketch food chains, nutrient cycles, and biomes. Drawing helps you remember relationships better.

Connect to Real Life

Look for examples in nature around you - a garden is a small ecosystem with biotic and abiotic factors.
