- 1what is ecologythe branch of biology that deals with the relation of organisms with each other and their physical surroundings
- 2name the 5 levels of organization ecologists use1. organism
2. population
3. community
4. ecology
5. biosphere - 3what is an organisman individual animal, plant or single celled life form living
- 4what is an ecosystema biological community of interacting organisms
- 5name the seven characteristics of living things1. they are all made from the same basic chemical ingredients
2. they are composed of cells
3. they require water and a source of energy
4. they can reproduce and grow
5. they have a limited life span
6. they can respond to their surroundings
7. they have the ability to move - 6what is the difference between biotic and abioticbiotic is living and abiotic is not living
- 7what is a habitatthe environment in which the organism usually lives
- 8what are predator and give an examplepredators are organisms that hunt an eat each other for example fox eating a rabbit
- 9what are prey and give an exampleprey are organisms which are hunted and killed and consumed by other organisms for example a gazelle is the prey of a cheetah who is hunting it
- 10what is a producerthey are plants because they produce their own food inside themselves they are the first organisms in the food chain
- 11what are consumersa consumer is an organism that eats food provided by plants or animals
- 12what is a primary consumera primary consumer is a one that feeds on producers
- 13what is a secondary consumera consumer that feeds on the primary consumer
- 14what is a tertiary consumera tertiary consumer is a consumer that feeds on the secondary consumer
- 15what is the difference between autotrophs and heterotrophsautotrophs produce their own food and using photosynthesis and heterotrophs cannot synthesize their own food so they rely on other organisms
- 16what is an omnivorean omnivore is an organism that eats both plants and animals
- 17what is a scavengerscavengers are organisms that feed on bodies of animals that are already dead
- 18what is a carnivorea carnivore is an organism that only eats other animals
- 19what is a herbivorea herbivore is an organism that only eats plants
- 20what is a food chain and explain how it worksa food chain shows a series f events when one organism eats another and obtains energy
must always begin with the producer then the primary consumer and then the tertiary consumer - 21what is a food web and explain how its worksa food web is a combination a food chains. food webs are for organism that eat more than just one food for example a rabbit doesn't only eat grass it also eats berries
- 22what do the arrows in a food chain or web representthe arrows point towards the animal that is getting the energy from another organism
- 23what is photosynthesisChlorophyll absorbs the sun’s energy.
It is this energy that is used to split water molecules into hydrogen and oxygen.
Oxygen is released from the leaves into the atmosphere.
Hydrogen and carbon dioxide are used to form glucose or food for plants. - 24during photosynthesis what do plant release during the dayoxygen (o2)
- 25during cellular respiration what do plants release during the nightcarbon dioxide (CO2)
- 26wat is the chemical formula for photosynthesis6CO2 + 6H2O -> C6H12O6 + 6O2
- 27what is the chemical formula for cellular respirationC6H12O6 + 6H2O + 6C02 + energy (ATP)
