Lesson 3

Question 1

• “The ability to do work”

Answer 1

energy

Question 2

require the consumption of energy which ultimately comes from the sun.

Answer 2

Biological activities

Question 3

the source of most of these sources.

Answer 3

The Sun, our nearest star

Question 4

-is light with wavelengths between 400 and 700 nm that

• is used by plants for photosynthesis.

Answer 4

• Photosynthetically active radiation (PAR)

Question 5

is crucial for climate processes because it absorbs carbon dioxide from the atmosphere and binds it to plants, soils, and harvested goods.

Answer 5

• Photosynthesis

Question 6

-Main source of energy
-it it essential for life on earth

Answer 6

Sun

Question 7

Process of producing food

Answer 7

Photosynthesis

Question 8

PAR means

Answer 8

Photosynthecally Active Radiation

Question 9

Those who are not reached by the sun is called

Answer 9

Chenosynthesis

Question 10

All animals depend on plants (directly or indirectly) called as

Answer 10

Consumer (heterothrops)

Question 11

Saprothrops

Answer 11

Decomposers

Question 12

When the energy enters the living system until it is degraded to heat

Answer 12

Ecological energetic

Question 13

Explains how energy in transformed from one to another

Answer 13

Laws of thermodynamics

Question 14

First Law

Answer 14

Law of conservation of energy

Question 15

Non-ramdom > ramdom form by the decomposers to simplier form called

Answer 15

Enthrophy

Question 16

All organism in an ecosystem are connected in an intercare manner called

Answer 16

Interconnection among organism

Question 17

Start Alive

Answer 17

Grazing Food Chain

Question 18

Start Dead

Answer 18

Detritus Food Chain

Question 19

Producers

Answer 19

Autotrophs

Question 20

Consumers

Answer 20

Heterotrophs

Question 21

Decomposers

Answer 21

Detritivores

Question 22

They are found in the upper trophic levels, where they cannot produce their food and consume plants or other animals for energy.

Answer 22

CONSUMERS (Heterotrophs)

Question 23

They can perform a process only a few kingdoms, like fungi, can. Decomposers, like herbivores and predators, derive energy, carbon, and nutrients from organic substrates for growth and development.

Answer 23

DECOMPOSERS (Detritivores)

Question 24

It focuses on how energy is captured, transferred, and utilized by living organisms and the efficiency of these processes.

Answer 24

• Ecological energetics

Question 25

Energy cannot be created or destroyed, only transformed from one form to another. In an ecosystem, solar energy is converted into chemical energy by plants, which is then passed through various trophic levels.

Answer 25

• First Law of Thermodynamics

Question 26

Living organisms' energy is non-random, but decomposers convert it into a random form when decomposable.

Answer 26

• Second Law of Thermodynamics

Question 27

This type of food chain begins with living green plants and progresses to grazing herbivores and carnivores.

Answer 27

Grazing Food Chain (GFC)

Question 28

GFC means

Answer 28

Grazing Food Chain

Question 29

• This type of food chain starts with dead organic matter and to organisms feeding on detritus(animal waste) and their predators.

Answer 29

Detritus Food Chain (DFC)

Question 30

DFC

Answer 30

Detritus Food Chain

Question 31

It is a states that only about 10% of the energy at one trophic level is passed on to the next. The remaining 90% is used for metabolic processes or lost as heat.

Answer 31

• The Ten Percent Law

Question 32

Who ecologist proposed the "The Ten Percent Law"?

Answer 32

Raymond Lindeman,

Question 33

They occupy a specific trophic level in the food chain, which can be multiple at a time

Answer 33

Organisms

Question 34

is a visual representation of energy within ecosystem trophic levels, starting with primary producers at the bottom and containing the most energy. Each step represents a different trophic level, with the width representing energy flow rate.

Answer 34

PYRAMID OF ENERGY

Question 35

• The Ten Percent Law, proposed by ecologist

Answer 35
