What is an autotroph?
|
An organism that can capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds. It is also called a producer.
|
|
|
What is a heterotroph?
|
An organism that obtains energy from the food it consumes. Also called a comsumer.
|
|
|
What are the different types of heterotrophs?
|
Herbivores (eats plants), Carnivores (eats animals), Omnivores eats (eats both plants and animals), Detritivores (eats dead matter and plant and animal remains), and decomposers (breaks down organic matter).
|
|
|
What is the equation for photosynthesis?
|
Carbon dioxide + Water (converts using sunlight energy) into Sugar + Oxygen.
|
|
|
What is the equation for Cellular Respiration?
|
Oxygen + Glucose (glucose is broken down in oxygen into...) Carbon Dioxide + Water + Energy.
|
|
|
Which organisms use Cellular Respiration?
|
Organisms that take in oxygen. Those that do not do so use fermentation.
|
|
|
Which organisms use photosynthesis?
|
Organisms that are plant or other autotrophs.
|
|
|
What part of the cell is involved with Cellular Respiration?
|
The exchange of glucose and oxygen for water and carbon dioxide happens in the mitochondria and then released through the cell membrane.
|
|
|
What part of the cell is involved with Photosynthesis?
|
It takes place in the Chloroplast which contains Chlorophyll (which is where it receive energy from the sunlight).
|
|
|
What is a Biome?
|
A group of ecosystems with same climate and dominant communities.
|
|
|
What is an ecosystem?
|
A collection of all the organisms that live in a particular place, togeter with their nonliving enviroment.
|
|
|
What is a community?
|
All the living things in an ecosystem.
|
|
|
What is Population?
|
The amount of one species in an ecosystem.
|
|
|
What is Symbiosis?
|
A relationship between two species living closely together.
|
|
|
What is predation?
|
An interaction in which one organism captures and feeds on another organism.
|
|
|
What is Parasitism?
|
When one organism benifits while another is harmed. TYPE OF SYMBIOSIS
|
|
|
What is Mutualism?
|
When both organisms benifit. TYPE OF SYMBIOSIS
|
|
|
What is Commensalism?
|
Where one organism benifits and the other is not affected. TYPE OF SYMBIOSIS
|
|
|
What are Biotic factors?
|
It has to be living or at one point in time living.
|
|
|
What are Abiotic factors?
|
Non-Living (Rocks, Water, Temperature)
|
|
|
What are three factors that can affect population size?
|
The number of births, deaths, and individuals that enter or leave the population.
|
|
|
What is a logistic growth?
|
When a population's growth slows or stops following a period of exponential growth
|
|
|
What is Exponential growth?
|
When the individuals in a population reproduce at a constant rate.
|
|
|
What is the carrying capacity?
|
The number of particular species that a given environment can support.
|
|
|
What is a Limiting factor?
|
A factor that causes population growth to decrease. (competition, predation, disease, climate changes, and human disturances can all cause it.)
|
|
|
What is Ecological Succession?
|
The series of predictable changes that occur in a community over time.
|
|
|
What is primary succession?
|
The development of a plant community on a bare surface.
|
|
|
What is secondary succession?
|
The development of a plant community following disturbances.
|
|
|
What is the Pioneer stage?
|
It is when the first plants come into the community. They are easy to grow and need minimal nutrients. (weeds, wildflowers, grasses)
|
|
|
What is the Seral stages?
|
They replace eachother by creating unfavorable conditions to the present stage and favorable to the next stage. (shrubs and small trees)
|
|
|
What is the Climax stage?
|
It is the final stage and will not be replaced by any other communities (oak and hickory forests)
|
|
|
What are the three types of pyramids?
|
The pyramid of energy *broadest at the base* (only 10% of the energy moves on to the next level), pyramid of numbers *not always the broadest at the base* (number of organisms at each level), and pyramid of biomass *always broadest at the base* (total dry weight of the organisms at each level.)
