Quiz on Living Organisms and Biodiversity

What are the two major groups of living organisms?

• Plants and Animals

• Fungi and Bacteria

• Insects and Birds

• Mosses and Ferns

Answer explanation

The two major groups of living organisms are Plants and Animals. This classification is fundamental in biology, distinguishing between autotrophic organisms (plants) and heterotrophic organisms (animals).

What is the largest classification group in the hierarchy of living organisms?

• Order

• Kingdom

• Phylum

• Class

Answer explanation

The largest classification group in the hierarchy of living organisms is the Domain. It encompasses all forms of life, including Bacteria, Archaea, and Eukarya, making it broader than Kingdom, Phylum, or Class.

How many kingdoms are there in the classification of living organisms?

• 7

• 3

• 5

• 10

Answer explanation

In biological classification, living organisms are typically divided into 5 kingdoms: Monera, Protista, Fungi, Plantae, and Animalia. Therefore, the correct answer is 5.

What type of competition occurs between members of the same species?

• Parasitism

• Interspecific competition

• Predation

• Intraspecific competition

Answer explanation

Intraspecific competition occurs when individuals of the same species compete for limited resources such as food, space, or mates. This type of competition can significantly impact population dynamics and survival.

What is biodiversity a measure of?

• Variety of different species and their numbers

• Amount of sunlight in an area

• Temperature variations

• Water availability

Answer explanation

Biodiversity refers to the variety of different species in a given area and their population numbers. It is a key indicator of ecosystem health, unlike factors like sunlight, temperature, or water availability.

What is the purpose of using scientific names for organisms?

• To avoid confusion

• To make names longer

• To use common names

• To simplify language

Answer explanation

The purpose of using scientific names for organisms is to avoid confusion. Common names can vary by region and language, while scientific names provide a universal standard that ensures clarity in identification.

What is the importance of taking a random sample when measuring biodiversity?

• To simplify calculations

• To increase sample size

• To reduce time spent

• To avoid biased data

Answer explanation

Taking a random sample is crucial for measuring biodiversity as it helps to avoid biased data. This ensures that the sample accurately represents the entire population, leading to more reliable and valid conclusions.

What do plants compete for in their environment?

• Food, territory, and mates

• Light, water, and minerals

• Shelter and warmth

• Space and air

Answer explanation

Plants primarily compete for light, water, and minerals, as these resources are essential for photosynthesis and growth. The correct choice highlights the key factors that influence plant survival and development in their environment.

What is a transect used for in measuring plant distribution?

• To measure animal movement

• To calculate plant height

• To observe plant life changes along a route

• To identify plant species

Answer explanation

A transect is a method used to observe plant life changes along a specific route, allowing researchers to assess how plant distribution varies with environmental factors.

Which technique is used to measure the biodiversity of animals?

• Quadrat sampling

• Capture/recapture technique

• Transect method

• Random sampling

Answer explanation

The capture/recapture technique is specifically designed to estimate animal populations and measure biodiversity by capturing individuals, marking them, and then recapturing to assess population size.
