Conservation of Biodiversity

A community of organisms that interact with each other and are affected by the abiotic, biotic, climatic, and edaphic factors surrounding them

Living : predation, competition, disease

Weather: rainfall, sunlight , temperature

Soil: type, moisture, pH

All the organisms in an ecosystem that belong to the same species eg all the foxes

all the different populations together in an ecosystem

the position an organism occupies in the food chain

from secondary consumers by eating them

from the sun by photosynthesis

only about 10% of energy from one trophic level is actually passed onto the next level, the rest is used for growth etc

to convert starch made during photosynthesis to protein -nitrogen needs to be in the form of nitrate salts which are made in the nitrogen cycle

food, water, medicine, recreation, spiritual/aesthetic

-seafood from oceanic ecosystems

-transpiration in large forests contribute to clouds which release fresh water

morphine from poppy -aspirin from willow

refers to all the different types of ecosystems on earth

need for many very different types of ecosystems to accomodate each different organism -niche help keep ecosystem healthy, by studying and maintaining biodiversity we keep our planet healthy

terrestrial - forest, grassland aquatic - salt,freshwater

high density of living organisms, easily upset with small changes

grazing animals -lots of insects and their predators

• lots of dissolved minerals - makes up most of earth’s water

• makes up less than 1% of earth water - home to almost half of all fish species

the wise management of a natural resource to prevent exploitation, destruction or neglect

forest management (replanting) • plans to prevent overharvesting fish • reduce consumption of resources by reuse, reduce,recycle
