photosynthesis and food webs

Question 1

what is photosynthesis?

Answer 1

photosynthesis is a process by which green plants make their own food

Question 2

what can green plants do?

Answer 2

that green plants can convert light energy into chemical energy in food

Question 3

what do plants require to photosynthesis?

Answer 3

that plants require carbon dioxide and water to photosynthesise

Question 4

what do plants produce as a byproduct of photosynthesis?

Answer 4

that plants produce oxygen as a by-product of photosynthesis

Question 5

what does photosynthesis create/release?

Answer 5

oxygen

Question 6

what is chlorophyll?

Answer 6

that chlorophyll (green pigment) is needed to trap light energy for photosynthesis

Question 7

where is chlorophyll found?

Answer 7

that chlorophyll is found in chloroplasts in green plant cells

Question 8

what do plants make during photosynthesis?

Answer 8

that plants make sugar (glucose) during photosynthesis

Question 9

how can the plants store this glucose?

Answer 9

that plants can store this glucose as starch

Question 10

what do plants use the glucose to make?

Answer 10

that plants also use glucose to make cellulose for plant cell walls

Question 11

what is the word equation for photosynthesis?

Answer 11

water + carbon dioxide (chlorophyll) (light) -> glucose + oxygen

Question 12

what are the basic parts of a leaf?

Answer 12

a) upper epidermis
b) lower epidermis
c) palisade mesophyll layer
d) spongy mesophyll layer
e) air spaces
f) guard cells surrounding stoma pores on the lower surface

Question 13

what may there be on the epidermis?

Answer 13

that there may be a waxy, waterproof covering (cuticle) on the epidermis

Question 14

how is water taken in?

Answer 14

that water is taken in by the roots of plants

Question 15

how does the water move up (photosynthesis)

Answer 15

that this water moves upwards through the roots and stems to the leaves

Question 16

what do herbivores eat?

Answer 16

that herbivores eat only plants

Question 17

what do carnivores eat?

Answer 17

that carnivores eat only animals

Question 18

what do omnivores eat?

Answer 18

that omnivores eat both plants and animals

Question 19

what do the arrows in a food chain indicate?

Answer 19

that the arrows in a food chain indicate the direction of energy flow

Question 20

what are green plants known as?

Answer 20

that green plants are known as producers as they make their own food by
photosynthesis

Question 21

what do consumers eat?

Answer 21

that consumers eat plants and other animals

Question 22

what is a food web?

Answer 22

that a food web is an inter-connected series of food chains

Question 23

what do predators eat?

Answer 23

predators eat other animals called prey

Question 24

what do food chains/webs begin with?

Answer 24

producers

Question 25

what is the source of energy for the producers?

Answer 25

the sun

Question 26

what are producers eaten by?

Answer 26

producers are eaten by primary consumers (herbivores)

Question 27

what are primary consumers eaten by?

Answer 27

primary consumers are eaten in turn by secondary consumers

Question 28

what are secondary consummate eaten by?

Answer 28

secondary consumers are eaten by tertiary consumers

Question 29

what does a pyramid of numbers in a diagram show us?

Answer 29

A pyramid of numbers is a diagram showing the number of organisms at
each stage of the food chain
