Exploring Earth's Biodiversity and Ecosystems

What is the definition of biodiversity?

• Biodiversity is the total biomass of all living organisms on Earth.

• Biodiversity is the study of how ecosystems function.

• Biodiversity is the variety of life in a particular habitat or ecosystem.

• Biodiversity refers to the number of species in a single organism.

Describe the characteristics of an ecosystem.

• An ecosystem only includes abiotic factors like soil and water.

• An ecosystem is solely made up of plants and animals without any interaction.

• An ecosystem consists of living organisms interacting with each other and their environment, characterized by biodiversity, energy flow, nutrient cycling, and ecological balance.

• Ecosystems are static and do not change over time.

What defines a savanna ecosystem?

• A savanna ecosystem is characterized by dense forests and high rainfall.

• A savanna ecosystem is defined by a cold climate with minimal vegetation.

• A savanna ecosystem consists mainly of wetlands and marshes.

• A savanna ecosystem is defined by grasslands with scattered trees, a seasonal climate, and diverse wildlife.

How does a rainforest differ from other forest types?

• Rainforests have low biodiversity and are mostly dry.

• Rainforests differ from other forest types by having high rainfall, humidity, biodiversity, and a multi-layered canopy.

• Rainforests are found only in cold climates.

• Rainforests consist of only one layer of trees.

What are the main features of a desert biome?

• High humidity and low temperatures

• Main features of a desert biome include low rainfall, high temperatures, extreme temperature fluctuations, and specialized plants and animals.

• Abundant rainfall and tropical plants

• Consistent mild temperatures year-round

What does the term 'tropical' refer to in environmental science?

• Regions between the Tropic of Cancer and the Tropic of Capricorn.

• Regions near the equator only.

• Areas above the Arctic Circle.

• Temperate zones between 30° and 60° latitude.

How would you describe a temperate climate?

• A temperate climate has high humidity and constant rainfall throughout the year.

• A temperate climate is characterized by extreme temperatures and no seasons.

• A temperate climate is always warm and does not experience cold weather.

• A temperate climate has moderate temperatures, distinct seasons, and regular precipitation.

What does arid mean in relation to climate?

• Arid means a climate with very low precipitation and dry conditions.

• Arid means a climate with moderate temperatures and seasonal changes.

• Arid describes a climate that is consistently cold and snowy.

• Arid refers to a climate with high humidity and frequent rainfall.

Define a wetland and its significance.

• Wetlands are only found in tropical regions.

• A wetland is a saturated land area that supports aquatic plants and is significant for wildlife habitat, water quality improvement, and flood mitigation.

• A wetland is a dry land area with no vegetation.

• A wetland is a type of desert that supports cacti.

What types of organisms are included in biodiversity?

• Animals, plants, fungi, and microorganisms.

• Only mammals and birds

• Only microorganisms and bacteria

• Only animals and plants
