Food Chain/Food Web 1
A _______________ makes its own energy and begins the food chain.
producer
The two factors that affect ecology
Biotic and abiotic factors
This type of competition occurs between members of the same species.
intraspecific
These organisms capable of producing their own food, also known as producers
autotrophs
Who is the producer out of the following?
1. kelp
2. shrimp
3. whale
kelp
What does a producer do? (2 things)
1. makes its own energy and
2. begins the food chain.
This refers to the number of individuals per unit area.
Population Density
This occurs when 2 different species have a close relationship within a community.
symbiosis
Since most primary producers use sunlight as the energy to drive photosynthesis they live in the ______________________ zone
photic
Organisms that must consume their energy, also known as a consumer
heterotrophs
A diagram that shows the transfer of energy with a single pathway is called ________________
a food chain
The maximum number of individuals of a particular species that a particular environment can support.
carrying capacity
Occurs when both species in the relationship benefit in some way
mutualism
When a plant or animal dies, organisms known as _______________release the energy within the organism’s tissues to the environment and break down the organism’s complex organic molecules into basic molecules
Decomposers
Cellular respiration is the opposite of
photosynthesis
List the levels of organization in ecology from biggest to smallest (there are 6)
Biosphere, Biome, Ecosystem, Community, Population, Species
Dolphins travel in pods or clumps is an example of
Dispersion
When one organism, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life
Parasitism
These show the amount of energy contained within each trophic level within a food chain or web
Ecological (Energy) Pyramid
Chemosynthesis occurs in the _____________ zone usually near hydrothermal vents that are rich in certain chemicals, like hydrogen sulfides.
Aphotic
A type of consumer that eats only meat is called a __________
carnivore
What's a carnivore?
A type of consumer that eats only meat
The remora fish attaches himself to a shark to gain a free ride & protection from predators. The shark is not affected. This is an example of
Commensalism
During the process of chemosynthesis, Carbon dioxide + water + hydrogen sulfide =
oxygen + sugar + sulfur
These are rich in certain chemicals, like hydrogen sulfides.
