FRP SCIENCE VC

Environmental science is an interdisciplinary academic field that integrates physics, biology, and geography to the study of the environment,

• True

• False

Define dependent variable

• a variable (often denoted by x ) whose variation does not depend on that of another.

• a variable (often denoted by y ) whose value depends on that of another.

• A variable is any characteristics, number, or quantity that can be measured or counted. A variable may also be called a data item.

• Machinery from the 1700's

is a population affected by its limiting factors?

• True

• False

Definition of a biotic factor

• a massive and extremely remote celestial object, emitting exceptionally large amounts of energy, and typically having a starlike image in a telescope. It has been suggested that quasars contain massive black holes and may represent a stage in the evolution of some galaxies.

• Organisms that inhabit ecosystems

• Non-living factor

• Living Organism

what the formula for exponential growth

• f(x)=(-b-4a)

• f(x)=1+0.9

Describe Symbiosis

• interaction between two different organisms living in close physical association

• free living, independent. It is a type of interaction in which individuals of two different species or two population function in very close association but don't affect one another adversely and beneficially

• The interaction between abiotic factors

• Process related to photosynthesis

percentage of energy lost during each trophic level

• 10%

• 90%

• 1%

• 0.10%

Plants go through a process called photosynthesis

• True

• False

Define producer

• any organism that can't make its own food

• any organisms big enough to obtain energy by feeding off lower-level consumers

• an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.

• Photosynthesizing organisms.

define the law of conservation of mass

• the law that the velocity of recession of distant galaxies from our own is proportional to their distance from us

• total energy of an isolated system remains constant; it is said to be conserved over time.

• that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed

• The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the light source.
