Ecosystems

Question 1

Order of size in leaves

Answer 1

Leaf 
Leaf tissue
Mesophyll cell
Chloroplast
Grana
Chlorophyll

Question 2

Photosynthesis process

Answer 2

Chlorophasts contains grana which contains chlorophyll and absorbs light energy to create glucose.

Or scientific equation
6Carbon Dioxide + water = 6glucose(c6h1206) + 6 oxygen + 6water

Question 3

What light do plants absorb?

Answer 3

Any light on the visible light spectrum but preferably red and blue right and they reflect green light.

Question 4

Producers / autotroph

Answer 4

At the base of the food chain and doesn’t rely on other organisms for food. Plants use photosynthesis to create food.

Question 5

Metabolism

Answer 5

Chemical equations that occur when an organism uses energy to grow and repair cells

Question 6

Cellular Respiraiton

Answer 6

When oxygen is used to move glucose and atp around the organism

Question 7

Aerobic respiration

Answer 7

The chemical breakdown of food saving oxygen. The reactions need enzymes, occurs in all body cells and releases energy.

Question 8

Glycolysis

Answer 8

Process by which glucose is converted into a simple form, during which energy is released.

Question 9

Cytosol

Answer 9

The fluid found inside cells.

Question 10

Kerbs cycle

Answer 10

Part of the aerobic respiration process in which carbon dioxide and ATP are produced.

Question 11

Electron transport : chain reaction

Answer 11

Part of the aerobic respiration process.

Question 12

Mitochondria

Answer 12

Small rod shaped organelles that supply energy to other parts of the cell. They are usually too small to be seen with light microscopes. Singular form is mitochondrion.

Question 13

Anaerobic respiration

Answer 13

The chemical breakdown of food without oxygen. The reaction needs enzymes, occurs in cells and realises less energy than aerobic respiration.

Question 14

Lactic acid

Answer 14

The product of anaerobic respiration in animals also known as lactate.

Question 15

Ethanol

Answer 15

An end prodyct of anaerobic respiration in plants, a form of alcohol

Question 16

Obligate anaerobes

Answer 16

Organisms that can respire only anaerobically, when there is oxygen.

Question 17

Species

Answer 17

A group of living organisms capable of interbreeding with each other but not with members of other species.

Question 18

Population

Answer 18

A group of individuals of the same species living in the same area at a particular time

Question 19

Community

Answer 19

More than one populations living in the same area at a particular time

Question 20

Ecosystem

Answer 20

Communities of organisms that interact with each other and their environment

Question 21

Producers

Answer 21

Organism at the base of the food chain that does not need to feed on other organisms; also known as an autotroph.

Question 22

Decomposers

Answer 22

Organisms that breaks down organic matter into inorganic materials

Question 23

Heterotrophs

Answer 23

Consumer

Question 24

Herbivore

Answer 24

Animal that eats plants only

Question 25

Primary consumers

Answer 25

The first consumer in a food chain; aka first-order consumer.

Question 26

Detritivores

Answer 26

Animals that feeds on and breaks down dead plant or animal matter.

Question 27

Ecological niche

Answer 27

The position of a species or population in its ecosystem in relation to each other.

Question 28

Competition

Answer 28

The struggle among organisms for food, territory and other factors.

Question 29

Parasitism Mutualism Commensalism

Answer 29

Where a parasite lives in/on the host and the parasite has the benefits but the host is affected negatively. Relationship between two different organisms in which both benefit Relationship between organisms where one benefits and the other is unaffected

Question 30

Interspecific competition Intraspecific completion

Answer 30

Competition between organisms of same species Same as above but different species

Question 31

Symbiotic relationship

Answer 31

Very close relationship between two organisms of different species. It may benefit or harm one of the partners.

Question 32

Carrying Capacity

Answer 32

The maximum amount of an organism's population in an ecosystem

Question 33

(X)iticdes

Answer 33

Something that kills (x)

Question 34

Bioaccumulation

Answer 34

Magnification of concentrations of a substance such as a nonbiodegradable pesticide along the food chain; also known as biological magnification
