|
What are the main parts of a plant?
|
-leaves
-roots -stems |
|
|
transpiration
|
the loss of water in plants through its leaves
|
|
|
What is the main job of each plant part?
|
leaves-make food through photosynthesis
roots-act like anchors, suck up H2O stems-support the plant |
|
|
photosynthesis
|
the process which plants make food using water, nutrients from the soil, and carbon dioxide and sunlight
|
|
|
chlorophyll
|
the organelle in the plant that allows it to absorb light, energy and photosynthesis. It makes a plant GREEN.
|
|
|
What is the purpose of chlorophyll?
|
-enables a plant to absorb light energy so that it can produce food.
-makes a plant GREEN |
|
|
What are chloroplasts?
|
small chlorophyll containing bodies and plant cells
|
|
|
Why do some plants change color in the fall?
|
the leaves start making chlorophyll so other pigments in the leaves become visible
|
|
|
List steps of photosynthesis:
|
1-sunlight
|
|
|
What does a plant need for photosynthesis?
|
-light
-water -chlorophyll -carbon dioxide |
|
|
producers
|
a living thing, such as a plant, that makes it own food
|
|
|
consumer
|
an animal that eats plants, other animals, or both
|
|
|
ecosystem
|
a community of organisms and the environment which they live
|
|
|
How do living things interact with one another in an ecosystem?
|
they may eat one another, compete for space, or share homes
|
|
|
herbivore
|
an animal that eats ONLY producers, also called, first level consumers
|
|
|
carnivore
|
an animal that eats other animals, also called second level consumers
|
|
|
omnivore
|
an animal that eats plants and other animals
|
|
|
food chain
|
the transfer of food, energy between organisms in an ecosystem
|
|
|
decomposer
|
a consumer that obtains food, energy by breaking down remainders of dead plants and animals
|
|
|
What can happen next to food energy taken in by a second-level consumer?
|
it can be transferred to a third level consumer, or be broken down by a decomposer
|
|
|
food web
|
a diagram that shows the relationship between different food chains in an ecosystem
|
|
|
If all the mosquitoes in a pond died, what might happen next?
|
the carnivore that feeds on mosquitoes would starve or eat more of another kind of food. Either way it would mess up the food web.
|
|
|
energy pyramid
|
a diagram that shows how much food energy is passed from each level in a food chain to the next
|
|
|
what can happen to a food chain if the number of second level consumers increases?
|
the second level consumers may eat more of the first level consumers, wiping them out. Eventually the second level consumers starve because there are not enough first level consumers for them to eat.
|
|
|
What non-living materials are important to living things?
|
-water
-nitrogen -carbon -oxygen |
|
|
What part do decomposers play in the nitrogen cycle?
|
decomposers release nitrogen back into the soil
