  4. What is a species? • groups of individuals that belong to the same species and live in the same area. • a group of organisms so similar to one another that they can breed and produce fertile offspring. • assemblages of different populations that live together in a defined area. • is a collection of all the organisms that live in a particular place, together with their nonliving, or physical, environment. • is a group of ecosystems that have the same climate and similar dominant communities

  5. What is a population? • groups of individuals that belong to the same species and live in the same area. • a group of organisms so similar to one another that they can breed and produce fertile offspring. • assemblages of different populations that live together in a defined area. • is a collection of all the organisms that live in a particular place, together with their nonliving, or physical, environment. • is a group of ecosystems that have the same climate and similar dominant communities

  6.

  10. Autotrophs • Autotrophs - use energy from the environment to fuel the assembly of simple inorganic compounds into complex organic molecules (Producers) • Processes- photosynthesis and chemosynthesis.

  11. Heterotrophs • Heterotrophs - organisms that rely on other organisms for their energy and food supply (Consumers) • Herbivores • Carnivores • Omnivores • Scavengers • Detritivores • Decomposers

  12. Food Chains and Food Chains • Food Chain - a series of steps in which organisms transfer energy by eating and being eaten • Food Web - links all the food chains in an ecosystem together
