Ecology Flashcards
What is the Biosphere?
The biosphere is the whole world from the lowest to the highest.
What is a biome?
A Biome is the different environments around the world
What is an ecosystem?
An ecosystem includes all of the living things(plants, animals and organisms) in a given area, interacting with each other, and also with their non-living environments (weather, earth, sun, soil, climate, atmosphere).
What is a community?
This is all the different species that live in the same habitat at the same time.
What is the population?
A population is made up off all the organisms of one species living together in the same place (habitat) at the same time.
Individual
Each population is made up of many individuals. The genetic and physiological adaptions of an individual organism to its environment is an important aspect of ecology.
Interdependence
Within a community each species depends on other species. They depend on each other for: food, shelter, pollination, mates and seed dispersal etc.
Habitat
A habitat is the place where an organism lives.
What are the word and chemical equations for photosynthesis?
Word equation: carbon dioxide + water light energy
———–>glucose + oxygen
Chlorophyll
Chemical equation: 6CO2 + 6H2O —> C6H12O6 + 6O2.
Where does photosynthesis happen?
In the leaf.
In the leaf what transports water?
Xylem
In the leaf what transports food?
Phloem
In the leaf what is the waterproof upper layer that prevents water loss called?
Waxy cuticle
In the leaf what is the transport layer - allows lots of light through called?
Upper epidemis
In the leaf what contains chlorophyll - traps sunlight energy?
Chloroplasts
In the leaf what is a pore that allows gases into and out of the leaf called?
Stoma
In the leaf what are the two cells that can change shape to open or close the stoma called?
Guard cell
