• A producer is an organism that is able to absorb energy from the sun through photosynthesis
• An ecosystem is a very large ecological area on the earth’s surface, with fauna and flora (animals and plants) adapting to their environment
• Nutrient cycling is a set of processes whereby organisms extract minerals necessary for growth from soil or water, before passing them on through the food chain - and ultimately back to the soil and water
• A food chain is a complex interconnection of all the food chains in an ecosystem
• A food chain is the connections between different organisms (plants and animals) that rely on one another as their source of food
• An ecosystem is a community of plants and animals that interact with each other and their physical environment
• A decomposer is an organism such as a bacterium or fungus, that breaks down dead tissue, which is then recycled to the environment
• A consumer is an animal that eats animals and/or plant matter
