Environmental Biology (3)

Half of the rain forests are destroyed by humans cutting down cutting down trees, growing crops, grazing cattle, and building settlements.

Microbes are the many thousands of species of bacteria and fungi and floating phytoplankton. they break down the food we eat,  help purify water and they help keep us alive.

• -The one way flow of high-quality energy
• -Cycling of nutrients 
• -Gravity

Water Vapor, Carbon Dioxide, Methane, Nitrous Oxide and Ozone.

An individual living being

Group of organisms that have a unique set of characteristics that distinguish them and can mate and produce fertile offspring

Group of individuals of same species living in a particular place

Populations of different species living in a particular place and potentially intreating with each other

community of different species interacting with one another and their nonliving environment of matter and energy

part of the earth's air, water,and soil where life is found

-Get energy from the sun 

-Survives on geothermal energy from the earth's interior

Organisms that uses solar energy or chemical energy to manufacture the organic compounds it needs as nutrients from simple inorganic compounds obtained from its environment

Feeds on the tissue of the producers or the consumers

animals that eat plants (herbivores; giraffes and caterpillars)

Animals that eat meat (carnivores; lion and fish)

Feed on the flesh of other carnivores (ex; tigers and hawks)

Eat plants and other animals (ex Humans, Pigs and Rats)

Organisms that a feed on dead organisms that were killed by other organisms or died naturally (ex; Vultures)

Feed on the wastes or dead bodies of other organisms (Detritivores)

Consumers in the process of obtaining their own nutrients, release nutrients form wastes or remains if plants and animals and then return these nutrients to the soil

Debris; parts of dead organisms and castoff fragments and wastes of living organisms

• 1st Producers (plants)
• 2nd primary Consumers (Herbivores)
• 3rd Secondary Consumers (Carnivores)
• 4th Tertiary Consumers (Top Carnivores)

All organisms that are the same number of energy transfers away from (feeding level)

The dry weight of all organic matter contained in its contained in it organisms that can be supported at each trophic level in a food chain or web

The rate at which an ecosystems producers convert solar energy into chemical energy in the form of biomass found in their tissues

the rate at which producers use photosynthesis to produce and store chemical energy minus the rate at which they use some of this stored chemical energy through aerobic respiration

• -Biogeochemical cycle that collect, purifies and distributes the earth's fixed supply of water from the environment to living organisms and the n back to the environment
• -Powered by energy from the sun and involves precipitation evaporation and transpiration.

• -taking large quantities faster than the nature can replace it 
• -clear vegetation to increases more runoff 
• -urban development

The flow of essential elements from the environment to living organisms and back to the environment.

• Transportation 
• cutting trees 
• burning fossil fuels

The basic building block of carbohydrates, fats, proteins, DNA, and other organic compounds necessary for life
