Key terms (easy)
This is something that is able to make it’s own food. The opposite of a consumer.
What is a producer?
This would happen if there was no more food. (In general)
Everything would die of starvation.
O2 is the product of this process.
What is Photosynthesis?
Abiotic and biotic
They are oposites. Abiotic is non living and biotic is living.
When this type of animal is removed from the ecosystem it will case a trophic cascade
A factor in an ecosystem that is NOT living.
What is abiotic ?
This would happen if all of the sea otters on earth vanished.
Sea urchins would over populate and consume all the kelp.
A lion is an example of this trophic pyramid level
What is a tertiary consumer?
Herbivore and omnivore
half in a whole. Herbivore is kind of like half of an omnivore, since omnivores eat both meant and vegetables.
This is the role that decomposers play in an ecosystem.
break down animal/plant bodies and decompose the waste.
This an organism will only eat plants hence the beginning of the name.
What is an herbivore?
This would happen if there was no oxygen on Earth.
Everything would shut down and die out, since everything essentially survives on oxygen. Plants wouldn’t have enough time to make more since they need both CO2 and H2O. Which both contain oxygen.
An animal is an example of this factor
What is a biotic factor?
Photosynthesis and water
Part in a whole. Since water is an important thing that goes into photosynthesis it is considered a part of the whole, the whole being photosynthesi.
This non-living thing can effect a population size
An Abiotic factor
The process used by plants that making sugar(glucose).
What is photosynthesis? The word comes from the greek terms, photos, meaning light and synthesis, meaning putting together. When you put it together you got putting together in light.
This would happen if all of the rabbits disappeared?
All of the predators of the rabbits (in this case the rabbits are prey) would either have to find other prey, or would starve to death.
A mouse is an example of this type of consumer
What is a Primary consumer?
Food web and energy
a food web is showing the transfer of energ.
What is an energy pyramid?
A diagram in a pyramid shape that shows how much energy is transferred from predator to prey.
A factor that is essential to the survival of a species. This factor plays a big role in the population of the species.
What is a limiting factor?
This would happen if there were no humans on earth
Other species that have gone extinct due to humans hunting them down would probably be living, the same goes for the environmen.
Water is an example of this type of factor?
Abiotic limiting factor.
Biotic and photosynthesis
Things that photosynthesize ARE biotic or living. if they are not living, they can not produce glucose or oxygen.
This diagram shows how the energy is transferred from one organism to the next. It also shows predation.
What is a food web?
