Flashcards in Ecosystems Deck (49):
Producers and autotrophs
Organism at the base of the food chain that does not need to feed on other organisms.
The food making nprocess in plants that takes place in chloroplasts within cells.
The chemical reaction involving oxygen that moves the energy in gluecose into the compound ATP
The chemical breakdown of food using oxygen . The reaction needs enzymes, occurs in all body cells and releases energy.
Process by which gluecose is converted into a simple form during which energy is released.
Part of the areobic respiration process in which carbon dioxide and ATP are produced.
Electron Transport chain reactions
Part of the areobic repiration process
Small rod-shaped organelles that supply energy to other parts of the cell.
The chemical breakdown of food without oxygen. The reaction needs enzymes occurs in cells and releases less energy than aerobic respiration.
An end product of anaerobic repiration in animals also known as lactate
A group of living organisms capable of interbreeding with each other but not a different spieces.
A group of individuals just like a spieces living in the same area at a particular time
More than one population living in the same area at a time
Communities of organisms that interact with each other and their enviroment.
The study of eco systems
Organism at the base of the food chain that does not need to feed on the other organisms also known as an autotroph.
Organisms that break down organic matter into inorganic materials
The food making process in plants that takes place in chloroplasts within cells. The process uses carbon dioxide water and energy.
An organism that relies on other organisms for its food.
Animal that only eats plants
The first consumer in a food chain also known as first order consumer.
An animal that eats other animals
Animal that eats plants and other animals
Animal that feeds on and breaks down dead plant or animal matter
The struggle among organisms for food and territory
A parasite living in another species otherwise known as the host.
Relationship between two different organisms in which both benefit
Relationship between organisms where one benefits and the other is unaffected
Competition between different species
Intra specific competition
compettition between the same spieces
Predator- Prey relationship
Relationship between organisms that kills and eats another species for example a lion and a zebra
Very close relationship between two organisms of different species. It may benefit or harm one of the partners
The amount of an organism the eco system can handle.
Describes organisms that produce organic material using energy released from chemical reactions rather than light.
diagram that shows how the energy stored in one organism is passed to another
diagram showing several food chains joined together to demonstrate that animals eat more than one type of food
a level within a food chain, food web or food pyramid
a representation of the level of food energy at each level within a food chain
Pyramid of numbers
a representation of the population, or numbers of organisms, at each level within a food chain
Pyramid of biomass
a representation of the dry mass of organisms at each level within a food chain
the number of organisms within a population that are born within a particular period of time
the number of organisms within a population that die within a particular period of time
a rapid increase in number or size, represented by a J-shaped graph
the shape of a graph that shows a population increasing in number then reaching a plateau
Equilibrium, Plateau phase or steady state
a state in which conditions are balanced and there is neither growth nor a decrease in number; also known as steady state or plateau phase
