Ecosystems
This has interconnected food chains in an ecosystem.
Food Web
An organism that eats producers and therefore is the first eater in a chain/web.
Producer
How much energy is lost when Producers are eaten by Primary consumers?
10%
This is the basic unit of life.
cells
They transport both water and minerals through the xylem, and transports food energy through the phloem to the leaf and on to the rest of the plant.
leaf veins
This is a tiny organism that live in an ecosystem.
Microorganism
A CARNIVORE that feeds on the bodies of DEAD organisms
Scavenger
What is the main source of energy in an Energy Pyramid?
the Sun
This is most often a non-native species that spreads from a point of introduction to become naturalized and negatively alters its new environment.
Invasive Species
These are the long cells through which nutrients, such as sugars, are distributed in a plant.
phloem
An organism's particular role in an ecosystem (a prey, a consumer, a omnivore, etc.) is called...
Niche
An organism that eats primary consumers (the second eater in a chain).
Secondary Consumer
How much energy is lost when Tertiary consumers eat Secondary consumers?
0.1%
This a process used by plants and algae to make sugar (food) out of light, carbon dioxide, and water.
Photosynthesis
A system of tubes for transporting nutrients .
vascular system
These are physical characteristics of the ecosystem (weather, temperature, wind).
Non-living (abiotic)
The third eater in a chain...eats the secondary consumer.
Tertiary consumer
Which population on a Energy Prymid has the largest population?
Producers
A waste gas produced by cellular respiration (CO2).
carbon dioxide
These are the hollow cells of a plant that transport water and minerals to plant cells at the top of a plant.
xylem
This is an organism that cannot produce its own food, instead taking nutrition from other sources.
Heterotroph
This is an organism that makes its own food.
Autotroph
Where do decomposers belong on the Energy Pryamid?
outside...each level looses energy to decomposers.
This is an organism that lacks chlorophyll and gets its nutrients from dead or living organisms.
fungus
A chemical in food that keeps an organism alive and active.
