• A land with high rainfall, typically between 250 to 450 mm annually, is a forest.
• Forests are areas with high vegetation density, and the abundant rainfall supports the growth of a diverse range of plant and tree species.

Explanation

• An ecosystem includes all the living components (biotic factors) like plants, animals, and microorganisms, and non-living components (abiotic factors).
• Like soil, water, air, and sunlight, interacting with each other.

• Examples of parasites include tapeworms, fleas, and lice.

Explanation

Abiotic components refer to the non-living things in an environment, including:

• Physical elements: light, temperature, water, soil, air
• Chemical elements: minerals, nutrients, salts
• Geological elements: rocks, minerals, terrain

Explanation

• Biotic components refer to the living things in an environment.
• Including plants, animals, microorganisms, and fungi.
