ECOLOGICAL ENERGETICS

Question 1

include energy transformation which occur within the ecosystem

Answer 1

ecological energetics

Question 2

study of energy flow within an ecological system from the it enters the living system until it is degraded to heat and irreversibly lost

Answer 2

ecological energetics

Question 3

how does energy flows

Answer 3

through the consumer food chain or detritus food chain

Question 4

in ecological energetics, we consider (3)

Answer 4

• energy reaching an ecosystem
• energy trapped by green plants (photosynthesis)
• path energy flow from green plants to organisms of different levels

Question 5

describes and explain how energy is transferred from one form to another

Answer 5

law of thermodynamics

Question 6

states that energy can change forms but is neither created nor destroyed

Answer 6

law of conservation of energy (1st law of thermodynamics)

Question 7

energy has the ability to spontaneously change into a more dispersed and random form unless there is degradation of energy

Answer 7

2nd law of thermodynamics

Question 8

organisms can produce their own foods

Answer 8

autotrophs

Question 9

others must obtain their food by eating or consuming other organisms

Answer 9

heterotrophs

Question 10

food chain types (2)

Answer 10

• grazing food chain
• detritus food chain

Question 11

begins with living green plants and progresses to grazing herbivores and carnivores

Answer 11

grazing food chain

Question 12

starts with dead organic matter and to organisms feeding on

Answer 12

detritus food chain
