Explanation

• Insects are a group of animals that have three pairs of jointed legs, and many of them have one or two pairs of wings.
• Their body is divided into three main segments: head, thorax, and abdomen.
• Insects include a wide range of species, some of which suck blood (like mosquitoes) or nectar from flowers (like bees and butterflies).
• Insects also lay eggs.

Explanation

• Mammals are a group of animals that have babies that are born alive (viviparous), are warm-blooded (endothermic), have mothers that feed their babies with milk (lactation), and have fur, hair, or skin and a spine (vertebrates).
• Examples: humans, dogs, cats, bears, whales, dolphins, lions, monkeys, elephants and sharks etc.

Explanation

• Birds are a group of animals that lay eggs, are warm-blooded, have either a beak or bill, have feathers on their body, and have a tail, two legs, and two wings.
• Examples: sparrows, eagles, robins, and ostriches.

Explanation

• Reptiles are a group of animals that have dry, scaly skin, are cold-blooded, lay their eggs on land, and live in both water and on land.
• Examples: snakes, lizards, spider, tortoise, turtles, and crocodiles.

Explanation

• Amphibians are a group of cold-blooded animals that live in both aquatic (water) and terrestrial environments (land).
• They have moist, smooth skin that helps them to breathe and regulate their body temperature.
• Examples: frogs, toads, salamanders, and newts.

Explanation

• Fish are aquatic animals that live in water, have fins instead of legs, lay eggs in water, have a body covered in scales, and breathe using gills.
• They are a group of cold-blooded vertebrates that are well adapted to life in water.

Explanation

• Warm-blooded vertebrates, also known as endothermic vertebrates.
• Warm-blooded are animals that maintain a constant body temperature, regardless of the temperature of their surroundings.
• They are able to generate heat internally and regulate their body temperature, allowing them to maintain a relatively constant body temperature.
• Examples: birds and mammals.

Explanation

• Cold-blooded vertebrates are animals that take on the temperature of their surroundings.
• They are also known as ectothermic vertebrates.
• Their body temperature is regulated by the environment around them, and they often bask in the sun or seek shade to control their body temperature.
• Examples: fish, amphibians, and reptiles.

Explanation

Vertebrates are divided into two main groups based on temperature regulation:

1. Cold-blooded (ectothermic) vertebrates, which include: Fish, Amphibians and Reptiles
2. Warm-blooded (endothermic) vertebrates, which include: Birds and Mammals (including humans)

Explanation

Vertebrates are animals that have a backbone or spinal column. This group includes:

• Fish
• Amphibians
• Reptiles
• Birds
• Mammals (including humans)
