photosynthesis
why do plant need to do photosynthesis?
Because they need to make their own food
What kind of organism do cellular respiration?
Mostly animals but plants do it if they don't get enough sunlight.
What is a food chain? Draw one
What are the three cycles we talked about in class?
water, carbon, nitrogen
How does carbon get into plants?
they take in CO2
what are the products of photosynthesis?
Sugar and oxygen
what are the reactants of cellular respiration?
Oxygen, carbon/sugar,
How is a food web and food chain different.
A food web is made up of several food chains
How does water get from a plant to the atmosphere?
Transpiration
How does carbon get into a consumer?
They eat a plant which is made of carbon
What are the reactants in photosynthesis?
CO2, sunlight, and water
What are the products in cellular respiration?
Atp, CO2, and water
What role do decomposers have?
They eat dead material and cycle their matter back into the world.
How does water get from the dirt to the atmosphere?
evaporation
How does Carbon get in the atmosphere?
there are two answer for this
Animals breath out CO2
Decomposers breakdown dead carbon and cycle that into atmosphere
How does water get into a plant?
What is ATP?
That is the energy that is made from cellular respiration.
How does a food web show a cycle of matter and energy?
Because things like CO2 and oxygen move through other living things. Also, thing eat each other for energy and they create waste to make more food.
What is nitrification?
This is when bacteria changes the nitrogen in the soil into something usable for plants and animals.
Draw the carbon cycle
must include, CO2 in the atmosphere, something eating a plant, something dying and being broken down by decomposers and returning co2 to the atmosphere
What are the purposes of chloroplasts?
This is where photosynthesis takes place
this is where energy is stored
10%
Why is nitrogen important?
This is important for living things to make proteins.
how does an ecosystem get unbalanced? what happens when it does?
when one organism leaves, it cause the food chains to fall apart.
