Ecosystem Processes

Question 1

Equations for photosynthesis

Answer 1

photosynthesis is carbon dioxide + water —> glucose + oxygen + water. A balanced chemical equation for the process can be written as 6CO2 + 6H2O —> C6H12O6 + 6O2. Overall, photosynthesis uses light energy to convert carbon dioxide into a carbohydrate

Question 8

When a community of species depend on other species

Answer 8

Interdependence

Question 9

Increase in concentration of a pollutant in a organism

Answer 9

Bioaccumulation

Question 10

Increasing concentration of a pollutant in a food chain

Answer 10

Biomagnification

Question 11

the role of chloroplasts in photosynthesis

Answer 11

Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant.

Question 12

Waxy cuticle

Answer 12

Waterproof upper layer prevent water loss

Question 13

Upper epidermis

Answer 13

Transparent layer allowed lots of sunlight through

Question 14

Chloroplast

Answer 14

Contains chlorophyll that trap sunlight and creates energy

Question 15

Palisade cells layer

Answer 15

Tightly packed self with lots of chloroplasts. Photosynthesis occurs here

Purple leaves and poor plant growth

Question 24

Yellow leaves with brown spots and poor plant growth.

Question 25

Magnesium

Answer 25

To make Chlorophyll which is required for Photosynthesis.

Yellow leaves with brown spots and poor plant growth.

Question 26

Why do farmers use fertiliser in plants

Answer 26

To increase the plants amount of nutrients to make healthy crops

Question 27

word and chemical equations for respiration.

word and chemical equations for respiration.

Answer 27

Aerobic= Glucose + oxygen to energy + carbon dioxide + water
C6H12O6 to 6C02+ 6H20+ 38

Anaerobic= Glucose to lactic acid + energy + 2
C6H1206 to C3H603

Question 28

compare aerobic and anaerobic respiration.

Answer 28

Aerobic respiration occurs during normal activities when enough oxygen is available.

Anaerobic respiration Because during vigourous exercise when there is a lack of oxygen available

Question 29

Ecosystem

Answer 29

And ecosystem is a part of a biome. It includes all living things in a given area, interacting with each other, and also With their non-living environments

Question 30

Community

Answer 30

This is all different species that live in the same habitat at the same time.

Question 31

Population

Answer 31

A population is made up of all organisms of one species living together in the same place (habitat) at the same time.

Question 32

Habitat

Answer 32

a habitat is the type of natural environment in which a particular species of organism lives.

Question 33

Biosphere

Answer 33

•The volume of the earth’s surface where

organisms can be found.

Question 34

Biome

Answer 34

•The biosphere is made up of several types of
biome.
• These are classified due to their major
vegetation types, for example TUNDRA or
TROPICAL RAINFOREST.

Question 35

Niche

Answer 35

DescriptionIn ecology, a niche is the match of a species to a specific environmental condition. It describes how an organism or population responds to the distribution of resources and competitors and how it in turn alters those same factors.

Question 36

why bioaccumulation has a greater affect on top predators in a food chain

Answer 36

This is biomagnification, and it means that higher-level predators-fish, birds, and marine mammals-build up greater and more dangerous amounts of toxic materials than animals lower on the food chain.

Question 37

Biology pollutant

Answer 37

DescriptionBiological pollution is the impact of humanity’s actions on the quality of aquatic and terrestrial environment. Specifically, biological pollution is the introduction of non-indigenous and invasive species.
