| what is an ecosystem? | it is a community of living/non living organisms interacting with each other |
| what is a biome? | its a large geographical region that has similar ecosystems |
| +what are five examples of biomes | desert, grassland, tundra, tropical rainforest, freshwater |
| what is abiotic? Give one example | it is the nonliving factors that influence a living thing E.G.water |
| what is biotic? give one example | it is the living organisms in the environment e.g. insects |
| what is photosynthesis | it is the transfer of light (sun) energy to chemical energy. The plant uses this energy as fuel |
| what five things provide energy to the plant | -sun
-water
-chlorophyll
-nutrients in soil
-carbon dioxide in air |
| what is a four ways in which plants use food? | -Food nutrients move through the plant by sap
-Food energy is stored in roots
-Food is used for plant growth
-Food is used for energy |
| what is a food chain | its the order of organisms in which food is transferred |
| draw a food chain with five trophic levels | hawk - snake - frog - grasshopper - wheat |
| what is a food web | its all the food chains within an eco system interacting with each other |
| what is a food pyramid? | it represents the loss of energy throughout the trophic levels |
| draw a food pyramid with four trophic levels | human
-birds
-grasshopper
-wheat |
| what does photo mean and what does synthesis mean | photo-light
synthesis- putting together |
| what gives a plant its green colour | chlorophyll |
| what is ecological succession and use a forest fire to describe that process | it is when a change happens within an ecosystem and that eco system slowly grows back over time
-a forest fire occurs-the trees,shrubs, grass and insects are burned
-animals disappear
-slowly,grasses shrubs,insects ,small animals came back,until it climaxes and returns to its former self |
