ecosystem`s organisation
what is the organism
Individual living thing
what is the biotic factor
all living organisms in ecosystem. like plants, animals, human
Who are the primary consumer?
Primary consumers make up the second trophic level. They are also called herbivores. They eat primary producers—plants or algae—and nothing else. For example, a grasshopper living in the Everglades is a primary consumer.
What are the 3 large categories of environmental problems?
Pollution, Destruction of wildlife, Global warming
Layer of the planet Earth where life forms can exist.
biosphere
describe all interactions between biotic factors
Competition: relationship where organisms (same or different species) try to use the same resource
Predation - food chains and food webs (organisms eat each other to get energy)
Symbiosis: relationship in which at least one organisms benefits from another. it has types like: Mutualism, Commensalism, Parasitism
Definition of the food chain.
is the sequence of transfers of matter and energy in the form of food from organism to organism.
List 5 greenhouse gases.
Carbon dioxide, methane, nutrious oxide, water vapor, fluorinated gases
what is the differences between population and community
population-Group of organisms of the same species.
community-Group of organisms of different species.
"the energy from the sun is transformed into energy that organisms can use" which process is it
photosyntesis
Name at least 3 decomposers.
Fungi, bacteria, invertebrates-worms, insects
How does greenhouse effect occurs?
The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat
list 3 biomes
tundra, taiga, desert, grassland, rainforest, temperate forest
3 types of interact between biotic factors.
Predation
Competition
Symbiosis
Difference between food chain and food web
A food chain is a basic network that shows the linear flow of nutrients and energy from one trophic level to another. A food web is a multitude of food chains that are interconnected at many trophic levels.
What is the solution of global warming?
Planting trees, switch to eco-transport, Switch to another method of energy extraction, such as wind turbines, solar panels, etc.
examples to population of animals
example: lion pride
list all trophic levels. and describe them
Producers: autotrophic organisms
Transform the energy from the sun into sugars
Consumers: heterotrophs organisms
Feed on producers or other consumers.
Decomposers:
Feed on dead organisms and turn them into simple substances.
Give an example for a food chain. Describe it
examples
How do wind turbines work?
The kinetic energy, or energy of movement, contained in wind, turns the turbine blades
