Flow of Energy
Heat
What are producers?
Give an example
an organism that makes its own food by using energy from its surroundings.
Examples: Grass, flowers, plants
What is the food web?
a diagram that shows the feeding relationships between organisms in an ecosystem
What is the role of decomposers in a food web
recycle energy from dead producers and consumers
what are energy inputs and outputs of photosynthesis?
inputs: energy from the sun, carbon dioxide and water
outputs: sugars, oxygen and chemical potential energy
10%
What are primary consumers?
Give an example
Primary consumers eat producers
example: insects, rabbits, tapirs
What is a food chain?
The pathway of energy transfer through various stages as a result of the feeding pattern of a series of organisms.
Cells and living things breath in _____ and breath out ______?
breath in oxygen and breath out carbon dioxide
what would happen if plants could not carry out photosynthesis?
if plants cannot take energy from the sun for food, there will be less energy in the producers which leaves less energy for all other levels.
In which level is there the LARGEST exchange of energy?
producers > primary?
Primary > secondary?
secondary > Tertiary?
Producers > primary
What are secondary consumers?
Give an example
Secondary consumers eat primary consumers to receive energy.
example: Fox, Snake, spider
what are trophic levels?
One of the steps in a food chain or pyramid.
example: producer, primary, secondary or tertiary consumers.
what organism takes in carbon dioxide?
Trees and plants
carbon cycle word question
Ms. butler
what happens to the 90% of energy lost between trophic levels?
It is lost to the environment between trophic levels
What is a tertiary consumer?
Example:
Tertiary consumers eat secondary consumers to receive energy.
example: Sharks, Lions, Hawks
Biosphere
the part of the earth where life exists
cellular respiration
how cells use oxygen to produce oxygen from food
figure out energy calculations
ms butler
Draw and label the food pyramid
on white board
Which level of the food pyramid holds the most energy?
Producers
nutrient
a substance in food that provides energy or helps form body tissues. its necessary for life and growth
explain and draw the carbon cycle
photosynthesis gives food, energy and carbon to organisms, organisms die and release carbon into air through decomposition, combustion puts Carbon into the air.
