Biodiversity and Ecosystem Characteristics

The video explains biodiversity, highlighting its importance as the variety of life in different environments. It compares biodiversity in gardens, showing how variety supports more life. Factors like water, sunlight, and temperature influence biodiversity. The video contrasts ecosystems like rainforests, deserts, and coral reefs, illustrating how environmental conditions shape biodiversity. Understanding and protecting biodiversity is crucial for healthy ecosystems and a thriving planet.

What does the term 'biodiversity' primarily refer to?

• The number of organisms in an area

• The variety of life forms in an area

• The size of organisms in an area

• The age of organisms in an area

Why does a garden with a variety of plants support more life?

• It is easier to maintain

• It has more sunlight

• It provides diverse food and shelter

• It is larger in size

Which factor is NOT mentioned as influencing biodiversity?

• Temperature

• Soil type

• Sunlight

• Water availability

Which of the following is a characteristic of a biodiverse ecosystem?

What makes tropical rainforests highly biodiverse?

• Cold temperatures

• Scarce water

• Consistent rainfall and dense vegetation

• Limited plant life

Which of the following is true about deserts?

• They are similar to rainforests
