Explanation

Detritivores feed on dead organic material, such as decaying plant and animal matter.

They are often called decomposers

Because they break down this organic matter into simpler substances, playing a key role in nutrient cycling in ecosystems.

Explanation

Water is the only known non-metallic substance that expands when it freezes

its density decreases and it expands by approximately 9% by volume.

Explanation

The color of a star is directly related to its temperature.

Hotter stars appear blue or white, while cooler stars appear red.

Explanation

The mantle is crucial as it plays a key role in geological processes a such as plate tectonics, which affect earthquakes, volcanoes, and the formation of mountain ranges.

The structure of the earth is divided into four major components:

1. the crust,
2. the mantle,
3. the outer core,
4. the inner core.

Explanation

Ice always floats because it is less dense than regular water.

Because frozen water molecules form a crystal

They take up more space and have a lower density than regular liquid water.

Explanation

The fungal bodies are formed by long, slender, thread-like structures called hyphae.

A collection of hyphae is known as mycelium.

Hyphae are of two types based on the presence or absence of a septum:

• septate
• Aseptate hyphae
  

Explanation

Solar cells, also known as photovoltaic cells, convert solar energy (sunlight) directly into electrical energy.

They work by using semiconductor materials to absorb photons from sunlight and release electrons, generating electricity.

Explanation

Hydrogen has an atomic weight of 1.00794u and accounts for 75% of the universe,

Thus making it the lightest and most abundant element in the universe.
