Answer 1

$\textbf{\huge{hello mate}}$

$\textbf{heterotrophic nutrition:-}$

• In this mode of nutrition, an organism is unable to synthesise food. It is of following types.

$\textbf{1.Holozoic Nutrition:-}$

• It is a type of nutrition when an organism takes in whole food and breaks it inside the body.
• (i) Those organisms that take various food items in a solid or liquid state are called Holozoic Nutrition.

For example - Amoeba

$\textbf{2.Saprophytic Nutrition:-}$

• It is a type of nutrition in which organism feed on dead and decaying matter.
• are those creatures, (Do not get your food from animal or plant),such as parasites called - tapeworm, dodder, etc.

For example - Fungi

$\textbf{3.Parasitic Nutrition:-}$

• It is a type of nutrition in which organisms feed on living host.
• they get their food from the organism, which dead animals are called saprophytes; Eg - bacteria, etc.

For example -Cuscutta

$\textbf{nutrition}$

• All organisms need energy to survive and to perform different metabolic processes occurring in the body.
• This energy is derived from food. Therefore, the action of receiving nutrients from food and other foods by organisms is called nutrition.

$\textbf{Types of Nutrition:-}$

There are two types of nutrition

$\bf 1. Autotrophic \: Nutrition$

• autotrophic literally means self-feeding, produces its food products by light-synthesis in the presence of light-rich carbon dioxide (C0_2) and water (H_2O) in light and the presence of chlorophyll. These organisms, which build their food themselves, are called autotrophs.

$\bf2. \: Contrary \: to \: autotrophs$

• some organisms may eat their food These creatures are called Heterotrophs

$\textbf{what is food? }$

• Food is what people and animals eat to survive .
• Food usually comes from plants and animals.
• It is usually eaten to get nutrition and energy .
• The food contains vitamins, carbohydrates, fat, protein etc.
• Food is any substance consumed to provide nutritional support for an organism.

$\textbf{Write the components of food?}$

• It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, fibre, or minerals.

$\textbf{Write the name of four heterotrophsheterotrophs?}$

• herbivores, carnivores, omnivores, scavengers, decomposers, and Detritivores.

$\textbf{Name any three parasitic nutrition?}$

• Examples of parasitic mode of nutrition are mosquito,ticks, lice, bedbugs , tapeworm .

Answer 2

Answer:

5- Saprophytic Nutrition – organisms obtain food from dead and decaying organic matter. These organisms are called saprophytes. Example: Yeast, Decomposers, etc. - Parasite Nutrition – the organisms live inside or outside the body of another organism.

1- the process of providing or obtaining the food necessary for health and growth.

"a guide to good nutrition"

2- any nutritious substance that people or animals eat or drink or that plants absorb in order to maintain life and growth.

3- The major components of feedstuffs are moisture, lipids, protein, fibre, carbohydrate, minerals and vitamins.

1 Moisture. Moisture (water) is an important diluent of the nutrients in feedstuffs. ...

2 Lipids and Fatty Acids. ...

3 Proteins and Amino Acids. ...

4 Carbohydrate. ...

5 Energy. ...

6 Minerals 4/2

4-There are four different types of heterotrophs which include herbivores, carnivores, omnivores and decomposers.

6- A parasitic plant is a plant that derives some or all of its nutritional requirement from another living plant. They make up about 1% of angiosperms and are found in almost every biome. All parasitic plants have modified roots, called haustoria, which penetrate the host plant, connecting them to the conductive system – either the xylem, the phloem, or both. For example, plants like Striga or Rhinanthus connect only to the xylem, via xylem bridges (xylem-feeding). Alternately, plants like Cuscuta and Orobanche connect only to the phloem of the host (phloem-feeding).[1][2] This provides them with the ability to extract water and nutrients from the host. Parasitic plants are classified depending as to the location where the parasitic plant latches onto the host and the amount of nutrients it requires.[3] Some parasitic plants are able to locate their host plants by detecting chemicals in the air or soil given off by host shoots or roots, respectively. About 4,500 species of parasitic plant in approximately 20 families of flowering plants are known.[4][3]
