AUTOTROPHS

Organism that can produce his own food.


  Green sulfur Bacteria

 Algae

 Cyanobacteria

NUTRITION IN PHOTOSYNTHETIC ORGANISMS

• Plants use inorganic minerals for nutrition.
• Roots absorb mineral nutrients as ions i soil water.
• The inorganic minerals in soil is formed with rock minerals, decaying organic matter, animals and microbes.

PHOTOSYNTHESIS

Is the process by the plant make their own food. The plant absorbs water from the roots and carbon-dioxide and light energy from the leaves, whit that things in leave make the photosynthesis, making food to the plant and releasing oxygen. 

For photosynthesis, plants need chlorophyll, which is a substance having green on the leaves. It is responsible for absorbing the right light for this process. In turn, chlorophyll is responsible for the characteristic green color of plants.

 

HETEROTROPHS

Is an organism that uses organic carbon for growth by consuming other organisms

• Herbivore
• Carnivore
• Omnivore

          

Heterotrophic nutrition is the nutrition obtained by digesting organic compounds prepared by other plants or animal tissues.All animals and non-green plants cannot make their own food; hence they depend on others directly or indirectly for their food supply.

HETEROTROPHIC NUTRITION TYPES

 

HOLOZOIC

SAPROPHYTE

PARASITIC

SYMBIOTIC

HOLOZOIC NUTRITION

This type of nutrition including food digestion, digestion of nutrients and excretion of wastes.

It's important because it maintain in equilibrium the food chain.

SAPROPHYTE NUTRITION

This kind of nutrition involves processing or decomposing the rotten foliage and dead or decaying organic matter of organisms. In this mode of nutrition, secretion of certain enzymes are released which break down the complex food into simpler forms.

FUNGI……...YEASTS……...MOULDS

PARASITIC NUTRITION

This nutrition is where an organism (known as a parasite) lives on the body surface or inside the body of another type of organism. It cause disease

SYMBIOTIC NUTRITION

In symbiotic nutrition both organisms are beneficial mutually.

FOOD PYRAMID

The food pyramid is designed to make healthy eating easier. Healthy eating is about getting the 

correct amount of nutrients – protein, fat, carbohydrates, vitamins and minerals you need to maintain good health.
