Matter and Energy in ecosystems

Global ecosystem of the Earth ECOSPHERE
Individuals of the same species which live in the same area POPULATION
It is an area which is occupied by a biocenosis and has its own physical and climatic characteristics BIOTOPE
All the living things that live in the same geographical territory BIOCENOSIS
It is a community of living things and their environment and includes all the interactions between them ECOSYSTEM
Natural environment in which an organism lives HABITAT
It affects animals'sleep patterns LIGHT
It can vary a lot in a terrestrial environment but not in an aquatic environment HUMIDITY
It increases considerably with depth in an aquatic environment PRESSURE
It is different in freshwater than in saltwater SALINITY
It has enormous influence on the development of live. TEMPERATURE
Factors that are variables of a biotope such as temperatura, light etc ABIOTIC
They take place between individuals of the same species INTRASPECIFIC RELATIONSHIPS
It is formed of at least one male and female of the same species, which mate, produce offspring and take care of their young. FAMILY
When a family is made of one male and one female, for example, pigeons. MONOGAMY
When a family is made up of one male and several females, for example, lions POLYGAMY
They are made up of individual organisms of the same species which can communicate with each other, and which often come from the same parent, for example, corals. COLONIES
They are made up of individuals from different families who live together to protect themselves, for example, gnus HERDS
They are made up of individuals of the same species but of different types that have obvious anatomical and physiological differences and which have an established division of work, for example, termites. EUSOCIAL COLONIES
They take place between individuals of different species INTERSPECIFIC RELATIONSHIPS
Two or more individuals from different species live closely together in a mutually beneficial relationship, for example, in lichens. SYMBIOSIS
It is a symbiosis that is only temporary. MUTUALISM
Two individuals from different species compete for access to a resource, such as territory, water or food. COMPETITION
One organism benefits by eating another species' leftover food, but the other organism isn't affected or harmed by its presence or by its behaviour. COMMENSALISM
One individual provides housing for an individual from a different species INQUILINISM
An individual from one species stalks, hunts, catches and feeds on an individual from a different species. PREDATION
One individual benefits from another individual which it seriously harms PARASITISM
It refers to the changes made by different organisms that occur in a species over many generations, which mean that they are better suited to their environment ADAPTATION
It flows through an ecosystem in one direction in an open system. It cannot be recycled in an ecosystem ENERGY
It flows through an ecosystem in a closed system. MATTER
It refers to all living things in an ecosystem that obtain matter and energy in a similar way and so occupy the same position in the food chain TROPHIC LEVEL
It is a linear representation of the feeding relationships between organisms at differetn trophic levels in an ecosystem. FOOD CHAIN
It is a graphical representatiion of the feeding relationships between species in an ecosystem, which combines several interrelating food chains FOOD WEB
They are autotrophic organisms. PRODUCERS
They feed directly on the producers PRIMARY CONSUMERS
They feed on primary consumers SECONDARY CONSUMERS
They feed on secondary consumers TERTIARY CONSUMERS
They transform organic matter into useful matter for producers DECOMPOSERS
It is a type of development which guarantees the needs of present generations but doesn't threaten the needs of future generations SUSTAINABLE DEVELOPMENT
