What is an Ecosystem?
A biological community of interacting organisms and their physical environment.
organisms that can make (produce) their own energy/food.
order in which matter and energy in the form of food is transferred from one organism to another.
feeding position in a food web.
What is a Autotroph
A process by which plants, algae, and certain microorganisms transform light energy from the sun into the chemical energy of food.
organisms that get their energy/food by eating (consuming) other organisms.
an organism that can make its own food by synthesizing organic nutrients from inorganic materials, using energy from sunlight or a chemical source to drive the process.
a sugar that the main source of chemical energy for cell functions in organisms from bacteria and plants to humans.
whats a consumer?
a sugar that the main source of chemical energy for cell functions in organisms from bacteria and plants to humans.
The process of getting energy from your food. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP
Food molecules ingested are broken down and then rearranged to become the molecules that compose the organism
organisms that get their energy/food by eating (consuming) other organisms
Producers and consumers are the same thing
true
false
what is glucose?
a sugar that the main source of chemical energy for cell functions in organisms from bacteria and plants to humans.
a model that shows the amount of biomass from one trophic level to the next.
a process by which plants, algae, and certain microorganisms transform light energy from the sun into the chemical energy of food.
an organism that obtains nutrients by consuming other organisms.
what is photosynthesis?
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
a organisms that can make (produce) their own energy/food.
an organism that can make its own food by synthesizing organic nutrients from inorganic materials, using energy from sunlight or a chemical source to drive the process.
order in which matter and energy in the form of food is transferred from one organism to another.
what is a food web?
order in which matter and energy in the form of food is transferred from one organism to another.
a model that shows the flow of energy from one trophic level to the next.
a model that shows the amount of biomass from one trophic level to the next.
the total mass of organisms in a given area or volume.
Where does the biomass and energy go?
Food molecules ingested are broken down and then rearranged to become the molecules that compose the organism.
Atoms in the products of photosynthesis (glucose and oxygen) are returned to the nonliving environment through:
The number and types of atoms you start with (reactants) must always equal to the number and types of atoms you end with (products)
feeding position in a food web.
What is a trophic level
an organism that obtains nutrients by consuming other organisms.
the total mass of organisms in a given area or volume.
feeding position in a food web.
a model that shows the amount of biomass from one trophic level to the next.
What is a biomass?
the total mass of organisms in a given area or volume.
feeding position in a food web.
process by which plants, algae, and certain microorganisms transform light energy from the sun into the chemical energy of food
process of carrying oxygen to cells, getting rid of carbon dioxide, and releasing energy.
