Ecology

Study of organisms interacting with their non living environment.

Eukaryotic organism

Surrounded by a distinct nucleus.

Prokaryotic organism

Surrounded by membrane, not nuclues

Bacteria

Single celled prokaryotic organism

Microbe

Moslty invisible rulers of the earth

Habitat

Place or environment where a population normally lives

Ecosystem

Community of different species interacting in a physical environemtn

Atmosphere

Thin layer of air around the planet

Troposphere

In layer

Stratosphere

Next layer, stretching 17-48 kilometres above earths surface

Biosphere

Portion of earth where living organisms interact

Greenhouse gases

Water vapour, carbon dioxide, methane nitrous and ozone

Biomes

Large regions like forests deserts and grasslands

Aquatic life zones

Numerous eco-systems, lakes oceans etc

Abiotic

Two types of components that make up the biosphere. Abiotic consists of non living components such as water, nutrients, solaar energy

Biotic

Living component, plants, animals

Range of tolerance

Variations in its physical and chemical environment

Law of tolerance

The existence, abundance, and distribution of a species in an ecosytem

Limiting factor principle

Too much or too of any abiotic factor can limit growth

Dissolved oxygen content

amount of oxygen gas dissolved in a given volume of water at a temp and pressure.

Salinity

amount of inorganic minerals or salts dissolved in a given volume of water

Producers

Self feeders

Photosysnthesis

Uses solar energy to tranforms chemicals

Chloroplasts

Cells that absorb sunlight

Chemosynthesis

Turning chemicals into complex compounds without sunlight

Consumers

Energy from feeding on other organisms

Decomposers

decompose

Detritus

Dead organic material

Detritivores

feed on detritus

Aerobic respiration

Uses oxygen to release enery from the compounds to fuel their life process

Anaerobic respiration

Break down glucose in the absence of oxygen

Biodiversity

Vital resource found in the earth's variety of specicies

Genetic diversity

Variety of genetic material with a population

SPecies diversity

Number of species present in different habitats

Ecological diversity

Variety of aquatic ecosytems

Functional diversity

energy and matter flow

Structural diversity

Physcial characteristics variations

Trophic level

Feeding level, organisms are assigned to producers or consumers or decomposers.

Biomass

Dry weight of all organic matter

Ecological efficiency

Percentage of energy transferred as biomass from one trophic level to anotehr

Pyramid of energy flow

Energy lost through travel between organism

Gross primary productivity

Rate at which eco systems converst energy

Net primary productivity

Rate at which photosyntheis to store energy minus the rate at which they use the energy

Soil

thin layer covering land, rock, nutrients, decaying matter

Soil horizion

Mature soils or developed soils over a long period of time form a horizontal layer of soils

Soil profule

cross sectional view of the soil horizons

Surface litter layer 0 horizion

top layer

Topsoil layer

porous mixture of paritally decomposed organic matter
