Question

5 . Write any two differences between:
(a) Xylem and pholem (b) Autotrophs and heterotrophs
(c) Herbivores and carnivores (d) Parasites and saprophytes​

Answer 1

Answer:

Xylem and phloem facilitate the transportation of water, minerals and food throughout the plant. Xylem carries water and minerals from the roots to the leaves. Whereas, phloem carries the food prepared by the leaves to different parts of the plant.

Summary. Autotrophs store chemical energy in carbohydrate food molecules they build themselves. Most autotrophs make their "food" through photosynthesis using the energy of the sun. Heterotrophs cannot make their own food, so they must eat or absorb it

HERBIVORES CARNIVORES

Consume only plant and their products Consume the flesh of other animals

Ratio of mouth to head is small. Ratio of mouth to head is too large.

The mouth opening is very small and consume food from their mouth. The mouth opening is very large and use their teeth for tearing the flesh apart.

Have broad, flat and short, teeth to grind and chew plant leaves, grains and seeds. Possess long, sharp and curved incisors and canines to tear flesh.

Answer 2

Answer:  Autotrophic Nutrition

i. In this type of nutrition, organisms can prepare their own food.

ii. Chlorophyll is required in this type of nutrition.

Heterotrophic Nutrition

i. In this type of nutrition, organic food is obtained from outside by different sources.

ii. Chlorophyll is not required.

Carnivores and herbivores

i . All plants and animals need energy to survive. ...

ii .  Herbivores are plant eaters. Carnivores are meat eaters. Omnivores eat plants and meat and insectivores eat insects.

Parasites and saprophytes​

i. Parasite is an organism that lives on or in another organism (called host), using it as a source of food and a place of temporary or permanent residence.

ii . Saprophyte is an organism that feeds on a decomposing matter from dead organisms.
