Living things kingdoms

Animal kingdom

Animal kingdom like all other living things, they carry out 3 vital function in order to live and grow:

Reproduction

Interaction

Nutrition

Animals can make other animals. This process is known reproduction. There are different types of reproduction. - Oviparous: They are born from eggs. - Viviparous: They give birth to their young.

Is the ability to respond to the environment. for example: when they are hot, they move into the shade.

Living things need energy. It comes from food because contains nutrients. Some animals get their food by eating plants, while others get their food by eating other animals. We call different types of animals herbivores, carnivores or omnivores.

Vertebrates Animals

Vertebrates animals are animals with backbone. All vertebrates have an internal skeleton that is made up of many bones. They can be viviparous such as dog, bear, elephant, dolphin or oviparous such as frog, eagle or lizard.

The body of a vertebrates is most commonly divided into head, body and limbs.

MAMMALS

They are vertebrates. They are some of the most intelligent and diverse animals on Earth. Mammals can walk, fly, swim or hop.

They are vertebrates. They live in fresh water or on land near the river. Most amphibians have four legs.

Invertebrates Animals

Invertebrate animals are animals without backbone. They don´t have an internal skeleton or bones. All invertebrates have one thing in common: they are oviparous.

ARTHROPODS

Arthropods are the biggest group of invertebrates. they have an external skeleton. there are 4 groups.

Crustaceans

arachnids

Insects

myriapods

MOLLUSKS

Mollusks have soft bodies. They can live in water and on land. there are three groups:

Cephalopods

Gastropods

Bivalves

ECHINODERMS

Echinoderms have a soft bodies with a hard, internal skeleton. Some main groups are:

Starfish

Sea urchins

Sea cucumbers

Annelids, Cnidariands and Sponges

Some others main groups of invertebrates are:

Annelids

Sponges

Cnidariands

Ecosystems

An ecosystem is an enviroment where living and non-living things interact. There are a lot of types of ecosystems: - Forest. - Grassland. - Deserts - Ponds. - Shoreline. - Urban ecosystems.

TYPES OF ECOSYSTEMS

Ecosystems can be classified into two groups: aquatic ecosystems and terrestrial ecosystems.

AQUATIC ECOSYSTEMS

most of the earth's surface is covered by water. there are two types of aquatic ecosystems: freshwater ecosystems, such as lakes and rivers, and saltwater ecosystems, such as seas and oceans.

TYPES OF ECOSYSTEMS

TERRESTRIAL ECOSYSTEMS

On the surface of the earth that is not covered by water we also find a multitude of different ecosystems. The forest, the desert, the prairie, the jungle or the bank of a river are terrestrial ecosystems.

Food Chains and food webs

All living organisms need energy to survive. Energy flows through food chains and food webs. The starting point for all food chains is the Sun . Food Chains:

Producers: They use energy from the sun to make their own food during photosynthesis. Plants and Algae. Consumers: They obtain energy when they feed on other living organisms. Primary consumers: They eat producers (hervibores and omnivores). Rabbits. Secondary Consumers: They eat primary consumers. (Carnivores and omnivores). Fox Descomposers: They descompose matter and release nutrients into the soil. Funghi and bacteria

Food Chains and food webs

Food Webs:

There can be lots of chains in an ecosystem. Most of these food chains are interconnected. Together, they form a food web
