extras:

• what types of organisms are often extremophiles 


  bacteria and archaea
• in ecology, what are secondary consumers 


  secondary consumers are organisms that eat primary producers
• give 4 resources that plants compete for 


  light, space, water and mineral ions
• what are functions (physiological) adaptations 


  the processes that take place within an organism that help them survive in their environment
• give 5 resources that animals compete for 


  food, water, mates, shelter and territory (space)
• what are structural adaptations 


  the physical features of an organism that help them survive in their environment
• in ecology, what are primary consumers 


  primary consumers are organisms that eat producers
• what is a population 


  a population refers to all the organisms of a particular species that live in the same habitat
• what is the purpose of transects in ecology 


  transects are used to observe and record changes in species distribution across different areas of a habitat
• what is an ecosystem 


  an ecosystem is an interaction of a community of living organisms (biotic) with the non-living (abiotic) parts of their environment
• how are quadrats used together with transects 


  quadrats are placed at regular intervals along a transect line to measure species distribution
• Give three examples of behavioural adaptations

  There are many, but here are a few:

  1 A squirrel running away from the sound or sight of a dog to avoid harm.

  2 A lizard sitting on a hot rock to warm up.

  3

  A spider spinning a web to catch flies.
• what might affect the distribution of dandelions in a field 


  factors like soil quality, sunlight, moisture, and proximity to a lake or woodland
• in ecology, what a producers 


  producers are organism that can produce their own food molecules, they are usually green plants or algae and produce their food molecules by photosynthesis
• in ecology, what is prey 


  prey is an animals that’s is hunted and killed by another animal for food
• in ecology, what are biotic factors 


  biotic factors (also known as living factors) refer to processes by which one living organism affects other living organism in its environment
• give 4 biotic (living) factors that can affect a community 


  availability of food, new predators arriving, new pathogens and one species out-competing another
• what’s is interdependence 


  interdependence is the idea that all organism in a ecosystems depend upon one another, and there are countless complex relationships between them; if one species is removed, it can affect the whole population
• what is a community 


  a community refers to all the populations of different species that live together in a habitat
• in ecology, what are tertiary consumers 


  Tertiary consumers are organisms that eat secondary consumers
