MATTER AND ENERGY IN ECOSYSTEMS

ECOSYSTEMS

An ecosystem is a set of interrelated beings living in a particular environment that influences them. In a distinct ecosystems: the biotope (physical environment) and biocenosis (living)

ECOSYSTEM = BIOTYPE + BIOCENOSIS

The biocenosis is constituted by all living things and we can call it community. Communities are formed by groups of organisms of different species. The bodies of the same species living in an interconnected ecosystem and the population consider a .

THE Biotic and abiotic


Living things in an ecosystem are influenced by other living things and the medium. Are what we call biotic and abiotic factors.

2) ABIOTIC NAMES OR ENVIRONMENTAL FACTORS CITED IN THE ACTIVITY

biotic We call the relationships established between living creatures of the same species (intraspecific relationships) or different species (interspecific relationships).

• RELATIONSHIPS Intraspecific

Within the same species can distinguish different types of relationships: thus we have families, neighborhoods, societies. Depending on the type of relationships are established grouping or aid competition among agencies within the group or not.

3) FIND THE KIND OF RELATIONSHIP OF EACH SPECIES

• INTERSPECIFIC RELATIONS

occur between individuals of different species and the main ones are: Predation

when one kills the other body and eats it. It would be a relationship (+,-). Parasitism

when an organism, host, who lives on another feeds without killing him but he causes injury. It would be a relationship (+,-).

Commensalism when one feeds on the remains left by another (0, +). Mutualism

when two individuals occasionally help (+,+). Symbiosis

when they help each other but have to live together (+,+). Competition

when fighting for the same resource. One wins and one loses (+,-).

INTERSPECIFIC RELATIONSHIPS OF MATTER AND ENERGY FLOW IN ECOSYSTEMS

ecosystems in the matter and energy are going some other agencies. But there are differences in the flow. The material is recycled but energy is lost as heat. 5) VIEW THESE ANIMATIONS. List the names of several producers, consumers and decomposers.

TROPHIC CHAINS AND NETWORKS

ecosystem agencies establish a series of trophic relationships. If we represent these relations we can get chains or food webs. Another way of representation are trophic pyramids.

6) FIND THE COMPONENTS OF THE YEAR food chain

POLLUTION


Look at the map of Madrid. Each point corresponds to a station for measuring air pollution. Click on two of them, choose a cleaner and writes at what times the pollution levels are higher. 8) POLLUTION IN MADRID
