  2. Ecosystems • Abiotic factors are non-living. • Bioticfactors are living. • Sunlight is the primary source of energy in ecosystems. • 10% of energy is transferred up through trophic levels. • The rest of the energy is used up in maintaining the organism and heat. • Herbivores are primary consumers.

  3. Ecosystems • Consumers on the next level up are called secondary consumers and are omnivores and small carnivores. • Tertiary consumers are medium or large carnivores. • Quaternary consumers are large carnivores. • Larger species populations are found at lower trophic levels. This is as result of the small level of energy that is transferred up from each level.

  4. Species Interactions • Predation has a predator and its prey. One species benefits and one species is harmed. • Competition is where species compete for available resources including food and shelter. • Mutualism is an interaction where both species benefit. • Parasitism is where onespecies benefits and the other is harmed but not killed. • Commensalism is when one species benefits and the other species is neither harmed nor benefits.

  5. Photosynthesis/Respiration • Photosynthesis takes in carbon dioxide and waterand produces oxygen and glucose. • Cellular respiration uses oxygen and glucose and releases carbon dioxide and water into the atmosphere.
