Natural Science - Term 4 - Week 8

In this lesson, we will engage in application tasks that help solidify our understanding of key concepts in Natural Science. Application tasks are designed to challenge you to think critically and apply what you have learned in practical scenarios. We will focus on using scientific vocabulary accurately and reflecting on our learning process.

Consider the term 'ecosystem.' An ecosystem includes all living organisms in a particular area, along with their physical environment. For instance, in a forest ecosystem, you would find trees, animals, soil, and water interacting. When we describe an ecosystem, we can use terms like 'biodiversity,' 'habitat,' and 'food chain' to explain the relationships within it.

In pairs, identify the components of an ecosystem using the vocabulary provided. List at least five components and categorize them into biotic (living) and abiotic (non-living) factors. After completing your list, share with another pair and discuss any differences in your findings. This will help reinforce your understanding of how these components interact within an ecosystem.

Now, it's your turn to create your own ecosystem! Draw a diagram of your ecosystem and label at least ten components, using the scientific vocabulary we have practiced. Write a short paragraph explaining how these components interact with each other. Once completed, be prepared to present your ecosystem to the class and explain your choices.

• Water
• Soil
• Plants
• Sunlight

Answer: Plants

Biotic factors are living components of an ecosystem, such as plants and animals.

• Habitat
• Niche
• Community
• Population

Answer: Niche

A niche refers to the role or function of an organism within its ecosystem.

Answer: Biodiversity refers to the variety of living organisms in a particular ecosystem.

Biodiversity is crucial for ecosystem resilience and health.

• Animals
• Plants
• Temperature
• Fungi

Answer: Temperature

Abiotic factors are non-living components, such as temperature and water.

Answer: A food chain shows how energy and nutrients flow through an ecosystem.

It illustrates the feeding relationships between organisms.

• A group of similar organisms
• A community of living organisms and their environment
• A single species in a habitat
• The physical environment only

Answer: A community of living organisms and their environment

An ecosystem includes both biotic and abiotic components interacting together.

Answer: Examples include animals and plants.

Both animals and plants are living components that interact within ecosystems.
