  • Abiotic components: Non-living environmental factors that have influence over the ecosystem (e.g. climate, light exposure, soil type).
  • Biome: Also known as a global-scale ecosystem; a large, distinct region of the Earth with similar climate, soil, plants and animals.
  • Biotic components: Living organisms that interact with the environment and other organisms within an ecosystem.
  • Consumers: Organisms that receive energy from consuming (i.e. eating) living organisms.
  • Decomposers: Organisms that break down organic material and release the nutrients back into the ecosystem.
  • Coniferous forest biome: A biome located at high latitudes, characterised by conifer trees and a cold climate.
  • Ecosystem: A natural system in which a community of plants and animals interact with each other and their physical environment.
  • Desert biome: A biome located around 30 ° north and south of the equator, characterised by extremely low precipitation levels and extreme daily temperature fluctuations.
  • Food web: A representation of the interactions between multiple producers and consumers within a specific ecosystem, shown through a series of different food webs.
  • Food chain: A linear relationship showing the biotic interactions within an ecosystem, from a producer to a final consumer.
  • Eutrophication: The growth of algae in a body of water due to excess nutrients, leading to the depletion of oxygen in an aquatic ecosystem.
  • Mediterranean biome: A biome located 40 - 45 ° north of the equator (and in isolated spots south of the equator), characterised by mild, moist winters and hot, dry summers.
  • Nutrient cycling: The transfer of nutrients through an ecosystem, from the decay of organic material into the production and energy of living organisms.
  • Temperate deciduous forest biome: A biome located around 40 - 50 ° north and south of the equator, characterised by deciduous trees (trees that shed their leaves) and moderate precipitation.
  • Tundra biome: A biome located in the far northern hemisphere, characterised by very cold conditions and permanently frozen soils.
  • Temperate grassland biome: A biome located in non-coastal areas around 30 -40 ° north and south of the equator, characterised by low precipitation and grasses as the major vegetation.
  • Tropical rainforest biome: A biome located near the equator, characterised by very high precipitation and sustained warm temperatures.
  • Producers: Organisms that convert energy from the environment (mainly sunlight) into sugars (glucose).
  • Savanna biome: A biome located around 15-30° north and south of the equator, characterised by high temperatures, very dry summers and very wet winters.
