The Organism In The Environment Flashcards
What are biological factors
Biological factors are factors effecting the abundance and distribution of organisms that are caused by other organisms, such as through competition for food
Describe a community
A community refers to all the populations of organisms that live in an area or ecosystem
Describe distribution of organisms
The spread of organisms in a area
What is ecology
Ecology is the study of living organisms
What is an ecosystem
An ecosystem is a fairly self contained area such as a lake or desert where all the organisms are contained
What is a habitat
A habitat is a small part of an ecosystem, where species live
What are physical features
Physical features are environmental features such as light, temperature and water that affect the abundance and distribution of organisms
What is a population
A population is all the organisms of one species living in the same habitat
What is a quadrat
A quadrat is a square frame used for sampling the abundance and distribution of organisms
What is biomass
Biomass is the mass of a living material, the mass of a living organism
What is a decomposer
A decomposer is an organism that causes decay of dead material, such as many fungi and bacteria
What is a primary consumer
A primary consumer is an animal that eats plants (a herbivore)
What is a producer
A producer is a organism that produces its own food such as a plant using alight energy to photosynthesise and produce glucose
What is a pyramid of biomass diagram
A pyramid of biomass is a diagram an which shows the biomass in different tropic levels of the food chain, often a pyramid as the later consumers are often larger
What is a pyramid of energy diagram
A pyramid of energy diagram shows the energy content of different tropic levels of he food chain, always a pyramid shape
What is a pyramid of number diagram
A pyramid of number diagram shows the number of individual organisms different tropic levels of a crook chain, often a pyramid shape
What is a secondary consumer
A secondary consumer is an mainland at eats the primary consumer
What is a tertiary consumer
A tertiary consumer is an animal that eats secondary consumers
What is a trophic level
A trophic level is a feeding level in a food chain or food web, such as producer, primary consumer…
What is the carbon cycle
The carbon cycle is the cycle of carbon thought different forms and the environment
What is combustion
Combustion is the burning of fossil fuels, puts carbon into the atmosphere
What is denitrifying bacteria
Denitrifying bacteria are solid bacteria that convert nitrates in the soil to nitrogen gas, releases nitrogen into the atmosphere
What are fossil fuels
Fossil fuels are fuels formed from organic material such as coal and oil, made from carbon
What is nitrifying bacteria
Nitrifying bacteria is bacteria in the soil which converts ammonium ions into nitrite ions. So that the nitrite ions can be converted into nitrate ions which plants can absorb the nitrates.
