Living Interactions
100
The study of living things and how they interact in their environment.
What is ecology?
100
This is the number of individuals in a certain area. For example: In the forest there are 5 butterflies per square meter.
What is population density?
100
the smallest unit of organization
What is an organism?
100
not living
What is an abiotic factor?
100
This type of symbiosis occurs when a predator and prey (hunting) is involved.
What is predation?
200
A habitat.
What is the place where the organism lives and that provides what it needs?
200
1. direct observation 2. indirect observation 3. sampling 4. mark-and-recapture.
What are the 4 ways of determining population size?
200
all the different population that live together in an area
What is a community?
200
biotic factor
What is a living thing?
200
This happens when a species must adapt to its environment for survival purposes. The species has no control over this concept.
What is natural selection?
300
Ecosystem.
What is all living and nonliving things that interact in a particular area?
300
Estimating
What is sampling?
300
This must be able to: eat food, requires shelter, must reproduce, and needs water.
What does something need in order for it to be considered "living?"
300
Water, sunlight, oxygen, temperature, and soil.
What are the 5 abiotic factors?
300
This happens when a species changes physically or behaviorally according to living conditions in order to survive.
What is adaptation?
400
This organization of what starts with organisms, then species, then populations, then communities, creating a huge ecosystem.
What is the organization of an ecosystem?
400
When a population or individuals moves OUT or LEAVES a population.
What is emmigration?
400
when a group of individuals move INTO a population
What is immigration?
400
all the members of one species that live in a particular area
What is a population?
400
1. competition 2. symbiosis 3. predation
What are the 3 types of interactions among living things?
500
This process requires water and sunlight to take part in plant growth.
What is photosynthesis?
500
Weather conditions, lack of food, and lack of space are all factors that prevent a population from increasing.
What are the limiting factors?
500
This study happens when a researcher/scientist labels a species in order to keep track of counting a population.
What is mark-and-recapture?
500
abiotic and biotic factors
What are the 2 major parts of an ecosystem?
500
This type of relationship occurs when 1 species benefits and the other remains the same/nuetral.
What is commensalism?
