Biology Standard 6

The Sun… Is the source of all energy on Earth Photosynthesis: plants/phytoplankton Autotrophs: orgs make own food GO SUNS!

Diagram that shows where energy goes in an ecosystem. Each level: trophic level Bottom Primary Producers: plants and phytoplankton; take sun energy  chemical glucose. Food Chains

Phytoplankton: Primary Producer

Plants: Primary Producers

Primary Consumer: Eats a Prim. Prod

Secondary Consumer: Eats a Prim. Consumer

Tertiary Consumer: Eats a Sec. Consumer

Consumers Org that eats a primary producer: primary consumer (herbivore) Org that eats a primary consumer: secondary consumer (carnivore) Org that eats a secondary consumer: tertiary consumer South Africa

Decompose rs Feed off dead organic matter in soil, release nutrients. Fungi and Bacteria Banana Slug

Decomposers

Amazon Food Chain Video

Grassland Biome Example Arrows show where energy is going! Prim. Producer Prim. Consumer Sec. Consumer Tert. Consumer

Make a Food Chain with your Neighbor Right Now!!!

As you go up the trophic levels, energy is lost. Rule of 10: 10% of energy in 1 trophic level is available to orgs at next level. Other energy is wasted as heat in env. Energy Pyramid

Energy Wasted as Heat

Food Webs Used to diagram feeding relationships, more complex. Shows all organisms in a system that eat each other.
