Objective:SWBAT explain why biodiversity is important in the biosphere.
What is the biosphere?
The biosphere is all life on Earth
What is biodiversity?Bio means: lifeDiversity means: varietyPut the two together, and you get:
Variety of Life or Biodiversity
Interdependence
Interdependence: Every species is linked, directly or indirectly, with others in an ecosystem.
Plants provide food, shelter, and nesting sites for other organisms.
Many plants depend upon animals for help in reproduction (bees pollinate flowers, provide nutrients (such as minerals in animal waste products).
All animals are part of food webs that include plants and animals of other species
Food Chain: sequence of what eats what in an ecosystem to obtain nutrition
Trophic Levels:The trophic level of an organism is the position it holds in a food chain.
Producers – an organism that makes its own food (plants)
Consumers – an organism that gets energy by eating other organismsHerbivores – plant eatersCarnivores – meat eatersOmnivores – plant and meat eaters
Tropic Level 1 - Producer
Tropic Level 2 - Primary Consumer
Tropic Level 3 - Secondary Consumer
Tropic Level 4 - Tertiary (Third) Consumer
.
