100
any kind of green plant. Green plants make their food by taking sunlight and using the energy to make sugar.
Producer (heterotroph)
100
an animal that naturally preys on others.
Predator
100
Use energy from the sunlight to make food fro the cell through the process of photosynthesis.
Function of Chloroplasts
100
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
Photosynthesis
100
a piece of wood, metal, or some other material having one thick end and tapering to a thin edge, that is driven between two objects or parts of an object to secure or separate them.
wedge
200
is a living creature that eats organisms from a different population.
Consumer (autotroph)
200
an animal that is hunted and killed by another for food.
Prey
200
an organelle in green plants containing the light harvesting pigment chlorophyll.
chloroplast
200
a substance that flows freely but is of constant volume, having a consistency like that of water or oil.
Liquid
200
an inclined plane around a cylinder.
screw
300
describes how energy and nutrients move through an ecosystem. At the basic level there are plants that produce the energy, then it moves up to herbivores. Then carnivores eat the herbivores, energy is transferred from one to the other.
Food Chain
300
Animals that eat plants.
Herbivore
300
one of the smallest parts of a plant or animal tissue.
Cell
300
a substance or matter in a state in which it will expand freely to fill the whole of a container, having no fixed shape (unlike a solid) and no fixed volume (unlike a liquid).
Gas
300
a rigid bar resting on a pivot, used to help move a heavy or firmly fixed load with one end when pressure is applied to the other.
lever
400
Food Chain
400
Animals that eat meat.
Carnivore
400
an atomic particle found in the nucleus. It is similar in mass to a proton but has no charge.
Neutron
400
firm and stable in shape; not liquid or fluid.
Solid
400
a simple lifting machine consisting of a rope which unwinds from a wheel on to a cylindrical drum or shaft joined to the wheel to provide mechanical advantage.
wheel and axle

Food Web
500
Animals eat both plants and meat.
Omnivore
500
an atomic particle found in the nucleus. It is similar in mass to the neutron but has a positive charge.
Proton
500
a sloping ramp up which heavy loads can be raised by ropes or chains
inclined plane
500
a wheel with a grooved rim around which a cord passes. It acts to change the direction of a force applied to the cord and is chiefly used (typically in combination) to raise heavy weights.
