WEEK 4: Matter, Energy, and Life in Ecosystem Flashcards
Any substance that has mass and takes up space
MATTER
Is the ability to do work
ENERGY
Energy in motion
KINETIC
Energy at rest
POTENTIAL
Are called autotrophs. They manufacture their own food.
PRODUCERS
Are called heterotrophs. They feed on plants, wastes of other living or remains of organisms
CONSUMERS
Consumers that eat plant products
HERBIVORES
Consumers that eat animal products
CARNIVORES
Consumers that eat both plants and animals product
OMNIVORES
Are fungis and bacteria that convert organic compound into inorganic forms which can be used again by living oganisms
DECOMPOSERS
Aids in photosynthesis
LIGHT
The effects of temperature on the absence or presence of animals in different habitats are varied.
TEMPERATURE/CLIMATE
Types of soil that plants do not grow well because water goes rapidly through the spaces between
SANDY
Retains water before drying it is sticky & not suitable for plant growth
CLAY
Good for agriculture & made up of particles of gravel sand & clay with the addition of humus
LOAM
Made up of very fine particles of soil or clay, deposited as sediments
SILT
No organisms will survive without this. It compromises a large percent of the body tissue of organisms
WATER
Plants that live in areas submerged in waters
HYDROPHYTES
Found in neither wet nor dry environment
MESOPHYTES
Found in almost waterless environment
XEROPHYTES
Removes water vapor surrounding the plants causing evaporation to take place
WIND/AIR
Deals with how energy is transferred in natural processes. It deals specifically with the relationship between heat, work, energy
THERMODYNAMICS
Energy may be transferred into a system. It may be transferred from one form to another. Energy is never created nor destroyed
FIRST LAW OF THERMODYNAMICS
With each successive energy transfer or transformation, less energy is available for work
SECOND LAW OF THERMODYNAMICS
Position occupied by an organism in the food chain
TROPHIC LEVEL
Weight of living matter per unit area of habitat
BIOMASS
