WEEK 4: Matter, Energy, and Life in Ecosystem

Any substance that has mass and takes up space

Is the ability to do work

Energy in motion

Energy at rest

Are called autotrophs. They manufacture their own food.

Are called heterotrophs. They feed on plants, wastes of other living or remains of organisms

Consumers that eat plant products

Consumers that eat animal products

Consumers that eat both plants and animals product

Are fungis and bacteria that convert organic compound into inorganic forms which can be used again by living oganisms

Aids in photosynthesis

The effects of temperature on the absence or presence of animals in different habitats are varied.

Types of soil that plants do not grow well because water goes rapidly through the spaces between

Retains water before drying it is sticky & not suitable for plant growth

Good for agriculture & made up of particles of gravel sand & clay with the addition of humus

Made up of very fine particles of soil or clay, deposited as sediments

No organisms will survive without this. It compromises a large percent of the body tissue of organisms

Plants that live in areas submerged in waters

Found in neither wet nor dry environment

Found in almost waterless environment

Removes water vapor surrounding the plants causing evaporation to take place

Deals with how energy is transferred in natural processes. It deals specifically with the relationship between heat, work, energy

Energy may be transferred into a system. It may be transferred from one form to another. Energy is never created nor destroyed

With each successive energy transfer or transformation, less energy is available for work
