Photosynthesis- 1.8-1.11

solar energy

0.023% of solar energy is captured by green plants and bacteria

Herbivore

A consumer that eats only plants.- primary

Decomposer

An organism that breaks down wastes and dead organisms

Photosynthesis

Carbon dioxide + water + Sunlight -> glucose + oxygen

Primary Productivity

NPP is mostly in oceans (total amount in world) and per unit area- estuaries

ecological efficiency

Percentage of energy transferred from one trophic level to another in a food chain or web

Plankton

Tiny organisms that float in the water and they are essential for life

scavengers

animals that feed on the bodies of dead organisms.

Natural ways greenhouse gas is admitted

decomposition, volcanoes, combustion, and respiration

Omnivores

eat both plants and animals-secondary

Respiration

glucose+oxygen-carbon dioxide+ATP+water

Food webs

more resilient

food web

network of complex interactions formed by the feeding relationships among the various organisms in an ecosystem

detrivore

organism that feeds on plant and animal remains and other dead matter- life,worms, beetles

carnivore

organism that obtains energy by eating animals- secondary

primary productivity

rate at which solar energy is converted into organic compounds via photosynthesis over a unit of time

net primary productivity

rate of energy storage by photosynthesizers in a given area, after subtracting the energy lost to respiration. NPP=GPP-R

gross primary productivity

total rate of photosynthesis in a given area. so producers convert solar energy into chemical energy as biomass
