Flashcards in EcoSystems Deck (59):
The food-making process in plants that takes place in chloroplasts within cells. The process uses carbon dioxide, water and energy from the sun.
Organism at the base of the food chain that does not need to feed on other organisms; also known as an autotroph
Chemical reaction for photosynthesis
Carbon dioxide + water -light and chlorophyll > glucose + oxygen
Chemical reaction for photosynthesis in chemical symbols
6CO2 + 6H2O - light and chlorophyll > C6H12O6 + 6O2
Process of photosynthesis
Chloroplasts contains Grana contains Chlorophyll absorbs Light energy used to make Glucose
The chemical reaction involving oxygen that moves the energy in glucose into the compound ATP. The body is able to use the energy contained in ATP.
What does ATP stand for?
Adenosine Tri Phosphate
The chemical breakdown of food using oxygen. The reaction needs enzymes, occurs in all body cells and releases energy.
Process by which glucose is converted into a simple form, during which energy is released.
The fluid found inside cells
Part of the aerobic respiration process in which carbon dioxide and ATP (energy) are produced.
Electron transport chain reactions
Part of the aerobic process.
Small rod-shaped organelles that supply energy to other parts of the cell. They are usually too small to be seen with light microscopes.
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 respiration in animals; also known as lactate
An end product of anaerobic respiration in plants; a form of alcohol.
Organisms that can respire only anaerobically in the absence of oxygen.
A group of living organisms capable of interbreeding with each other but not with members of other species.
A group of individuals of the same species living in the same area at a particular time.
More than one population living in the same area at a particular time.
Communities of organisms that interact with each other and their environment.
The study of ecosystems
Organism at the base of the food chain that does not need to feed on other organisms
Organisms that break down organic matter into inorganic materials.
Organisms that relies on other organisms for its food
Primary consumers/first-order consumer
The first consumer in a food chain (in the second trophic level).
Animal that eats only plants
An animals that eats other animals
Animal that eats plants and other animals
Animal that feeds on and breaks down dead plant or animal matter.
The position of a species or population in its ecosystem in relation to each other.
The struggle among organisms for food, territory, and other factors.
An interaction in which one species (parasite) lives in or on another species from which it obtains food, shelter, and other requirements.
Relationship between two different organisms in which both benefit.
Relationship between organisms where one benefits and the other is unaffected.
Competition between organisms of the same species.
Competition between organisms of different species.
Relationship between organisms in which one species kills and eats another species.
Very close relationship between two organisms of different species. It may benefit or harm one of the partners.
What is the difference between a decomposer and a detrivore?
A decomposer comes in the form of fungi or bacteria, whereas a detrivore can come in other forms like a worm, and they consume the waste of organisms
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.
Secondary consumer/second-order consumer
The second consumer in a food chain (in the third trophic level).
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.
The number of individuals moving into an area.
The number of individuals leaving an area.
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.
A state in which conditions are balanced and there is neither growth nor a decrease in number; also known as a steady state or plateau phase.
Zero population growth
The point at which birth and death rates balance each other out.
The maximum population size that a particular environment can sustain.
