What are the characteristics of living things?

Living things are made up of cells, obtain and use energy, grow and develop, reproduce, respond to their environment, and maintain homeostasis.

What is nutrition?

Nutrition is the process by which organisms obtain and use food for energy, growth, and repair.

What are the two types of nutrition?

The two types of nutrition are autotrophic nutrition and heterotrophic nutrition.

Define autotrophic nutrition.

Autotrophic nutrition is when organisms make their own food using sunlight (photosynthesis) or inorganic substances (chemosynthesis).

Define heterotrophic nutrition.

Heterotrophic nutrition is when organisms obtain their food by consuming other organisms.

What is respiration?

Respiration is the process of releasing energy from food to be used by cells.

Differentiate between aerobic and anaerobic respiration.

Aerobic respiration requires oxygen to produce energy, while anaerobic respiration does not require oxygen.

What is transportation in living organisms?

Transportation is the process by which substances are absorbed, circulated, and distributed throughout an organism's body.

Explain the process of transpiration in plants.

Transpiration is the loss of water vapor from the leaves of plants through their stomata.

What is excretion?

Excretion is the process of removing waste products from the body of an organism.

What is growth?

Growth is the increase in size and complexity of an organism over time.

Define reproduction.

Reproduction is the process by which new individuals of the same species are produced.

What is metabolism?

Metabolism is the sum of all chemical reactions that occur within an organism to maintain life.

What is homeostasis?

Homeostasis is the ability of an organism to maintain a stable internal environment despite changes in the external environment.

How do living things respond to their environment?

Living things respond to their environment through various stimuli, such as light, temperature, touch, etc.

What are the main life processes in humans?

The main life processes in humans include nutrition, respiration, circulation, excretion, reproduction, and growth.
