1. Recap - Ecosystems Across 3.  Living things in an ecosystem. 4.  An organism or plant that is able to absorb energy from the sun through photosynthesis. 6.  Creature that eats animals and/or plant matter. Down 1.  Non-living things in an ecosystem. 2.  An organism such as a bacterium or fungus, that breaks down dead tissue, which is then recycled to the environment. 3.  A global ecosystem. 5.  A community of plants and animals sharing an environment with non-living things. Study the food chain above. Identify the: Tertiary consumer Primary consumer Secondary consumer Producer Classify the animals as herbivore (h), omnivore (o) and carnivore (c). Label the nutrient stores: Biomass Soil Litter Label the nutrient transfers: Uptake by plants Input from weathered rock Loss by leaching Release as litter decomposes Loss in run off Input dissolved in rain Fallout as tissues die Fill in the gaps below. An _______________ is a natural system that is made up of plants, ______________ and the environment in which they live. The different components of an ecosystem are closely _____________ and depend on each other for _____________. If one component changes, there will be knock-on ____________ within the ecosystem. A food ____________ shows the direct links between different organisms that rely on each other as a source of food. A food _________ shows the complex hierarchy of plants and animals that rely on each other as a source of food. survival web ecosystem animals interrelated linked chain effects The Nutrient Cycle nutrient store nutrient transfer Factors that cause changes to an ecosystem human natural Extreme weather events, such as flooding and drought. Land use change, such as deforestation and hedgerow removal. Alteration to water and soils, such as land drainage or adding fertilisers. Climate change and global warming Fire caused by lightening strikes Spread of invasive species Hunting or trapping animals or birds Introduction of alien species 1 1 What is an ecosystem?  A A community of plants and animals sharing an environment with non-living things.  B The flow of energy between living organisms.  C A global biome such as the tropical rainforest.  D The pathways through which nutrients are constantly recycled. 2 Which of the following is a characteristic of a producer in an ecosystem?  A They are herbivores which means they only eat plants.   B They are carnivores.  C They produce their own food through photosynthesis.  D They break down dead plants and animals 3 Which biome is mainly found between 15° north – 15° south of the equator?  A Hot desert  B Tundra  C Tropical rainforest  D Savanna 4 Which of the following is not an example of a biome?  A Tropical rainforest  B Hot Desert  C Tundra  D Hedgerow 5 What is the transfer of nutrients through an ecosystem is known as?  A Food chain  B Food web  C The nutrient cycle  D A biome
