Explanation

• Decomposers are organisms that break down dead and waste products, releasing useful elements such as carbon, nitrogen, and phosphorus back into the soil and environment.
• This process is called decomposition, and it's an essential step in the nutrient cycle.

Decomposers include organisms like:

• Bacteria
• Fungi (such as mushrooms)
• Detritivores (such as earthworms and insects)

By breaking down organic matter, decomposers help to:

• Recycle nutrients
• Improve soil structure and fertility
• Support plant growth and development

• Fluid retention and swelling
• Edema (excess fluid in tissues)

Explanation

There are four fundamental states of matter: solid, liquid, gas and plasma

1. Solid: Fixed shape and volume; particles tightly packed.
2. Liquid: Fixed volume but takes container's shape; particles close but move.
3. Gas: No fixed shape or volume; particles far apart and move freely. 
4. Plasma: Ionized gas, found in stars, lightning; electrically charged.

Explanation

Magnesium deficiency can contribute to or exacerbate all of the following health issues:

• Painful joints: Magnesium helps regulate inflammation and muscle function, and deficiency can lead to joint pain and stiffness.
• Osteoporosis: Magnesium is essential for bone mineralization and density; deficiency can increase the risk of osteoporosis and fractures.
• Memory loss: Magnesium plays a role in neuronal function and synaptic plasticity; deficiency has been linked to cognitive impairment and memory loss.
• Diabetes: Magnesium helps regulate insulin sensitivity and glucose metabolism; deficiency can increase the risk of developing type 2 diabetes.

Explanation

Marasmus is a form of severe protein-energy malnutrition, characterized by a lack of sufficient protein and calories in the diet.

It is most commonly seen in children under the age of 5, particularly in developing countries where access to nutritious food is limited.

Marasmus is caused by a severe deficiency of protein and calories, leading to:

• Wasting of muscles and tissues
• Weight loss
• Fatigue
• Weakness
• Poor growth and development

Explanation

• Herbivores are animals that eat only plants, including leaves, stems, roots, flowers, fruits, and seeds.
• Examples of herbivores include cows, deer, rabbits, and elephants.
