- 1. Organisms such as plants and algae that can make food from raw materials such as carbon dioxide and water
- 3. Microorganisms that break down waste products and dead bodies
- 4. Special features that make an organism particularly well suited to the environment where it lives
- 7. A group of organisms that can breed together and produce fertile offspring
- 9. having enough food to feed the population
- 11. The amount of biological material in an organism
- 12. A sample area used for measuring the abundance and distribution of organisms in the field
- 17. records the numbers of organisms rather than just the type
- 21. The network of relationships between different organisms within a community, e.g. each species depends on other species for food, shelter, pollination, seed dispersal etc.
- 23. The type of farming where animals are grown in a temperature-controlled environment where their movement is limited, so they waste little energy keeping warm or moving
- 24. When gases in the atmosphere absorb energy radiated by the Earth and re-radiate it back towards the Earth, helping to keep it warm
- 26. A change in things like temperature or weather patterns in a part of the world or across the whole world
- 29. Model of feeding relationships based on the number of organisms at each level of a food chain
- 31. A living factor of the environment
- 33. The rise in the average global temperature
- 34. The permanent loss of all members of a species from an area or the world
- 35. A measure of the variety of all the different species of organisms on Earth
- 36. A measured line or area along which ecological measurements are made

- 30. The interaction of a community of living organisms with the abiotic parts of their environment
- 32. A measure of how common or rare a particular organism is in a given environment
