Some people and organisations like Greenpeace, fight for environmental conservation. For each of the animals, discuss how you think the organisms below are interacting with the abiotic environment. This is incorrect as individual organisms do not adapt, it is the populations or species which adapt over time. In each of the photos, the populations of animals are found in a specific area. We only have this planet and we need to look after it. Below are some points for the discussion. Learners will mark off parts of an ecosystem and must ideally be able to return to it regularly.

The last group of animals that we can discuss from this image are the decomposers. You may have heard of terms such as the biosphere and ecosystems in previous grades. Ex: water, surface rocks, and water, within which life occurs. Yes, it does make a difference. the bird then catches the insects as they fly up. A hummingbird feeding. As the interior of the leaves is transparent, the sunlight can travel through to the bottom parts of the leaves which are underground and contain the chlorophyll in order to photosynthesise. So, Lithops means 'stone-faced'! The umbrella thorn in the African savannah can survive temperatures ranging from 50C to below freezing.

Some organisms can make their own food, and other organisms have to get their food by eating other organisms. Animals have different adaptations which have enabled different species to live and function in different areas. Can you see the clear, fleshy middle parts of the leaves?

A key focus of the class is viewing soil health as the basis for ecological land management and discussing management practices to conserve and improve soils. Learners should take note of the water resources in their square, the slope of the land, and the type of soil and how this affects the organisms. How big can an ecosystem be? Only about 10% of the energy goes into new body cells and is available to the next animal when it gets eaten. This includes discussing: biotic, abiotic, classifications, habitats, niches, producers, consumers, decomposers, food chains, food webs, symbiotic relationships, and more! You can even draw some illustrations. The term autotroph comes from the Greek words autos meaning 'self' and trophe meaning 'nourishing'. So autotroph means 'self-feeding'.

In this type of . There are multiple food chains here. Symbiosis describes the way in which two different species living together in the same community, interact with each other over a long time period. There are many different types of pollution. There are several things that make up an ecosystem. The rat is an omnivore as it eats both plants and animals. How can we distinguish between the different consumers?

Write a few sentences where you explain why you think decomposers are important in an ecosystem and how they help an ecosystem to function. An ecosystem consists of the abiotic (non-living) environment and the biotic (living) organisms. [2 marks]. This loss of energy at each trophic level can be shown by an energy pyramid. In 2011, deep sea researchers discovered mussels living in symbiosis with bacteria that use hydrogen as a fuel source in chemosynthesis. Add highlights, virtual manipulatives, and more. Support companies that dispose of their waste responsibly. Structural: grooves on body form channels to mouth; strong hind legs, Behavioural: nocturnal habits, it stands in the specific position all night while water droplets condense on its body.
