SPECIES

Definition

• A species is a group of living organisms that are similar to one another.

• Members of the same species can reproduce and have offspring.

• The offspring can grow up and reproduce too.

• Species are the basic units used to classify living things.

Characteristics of a Species

• Members have similar physical features.

• They share many genetic characteristics.

• They can reproduce with each other.

• Their offspring are fertile (can have babies).

• They often have similar behaviors and life cycles.

Examples of Species

• Humans

• Dogs

• Cats

• Lions

• Tigers

• Mango trees

• Rice plants

• Butterflies

Importance of Species

• Helps scientists identify living things.

• Makes the study of organisms easier.

• Helps us understand biodiversity.

• Maintains the balance of ecosystems.

• Supports food chains and food webs.

Formation of New Species

• New species form through a process called speciation.

• This happens over thousands or millions of years.

• Changes in environment can lead to the formation of new species.

• Organisms gradually adapt to their surroundings.

Biodiversity and Species

• Earth contains millions of different species.

• Species include animals, plants, fungi, and microorganisms.

• Different species live in different habitats.

• Biodiversity helps keep ecosystems healthy and stable.

Threats to Species

• Deforestation

• Pollution

• Climate change

• Hunting and poaching

• Habitat destruction

• Invasive species

Fun Facts

• Scientists estimate there are about 8.7 million species on Earth.
