Animals Producers and Consumers

Animals Producers and Consumers

Living organisms can be grouped based on what they look like. when organisms are thought about as living together it is helpful to group them based on what they eat.
There are two groups : One group that produces food and the other group that consumes food.

Producers

Primary producers are organisms in an ecosystem that produce biomass from inorganic compounds (autotrophs). Producers make the food for all the other members of the community, they make their own food from simple substances carbon dioxide and water. Pants use light to make sugars from carbon dioxide and water.

Bacteria are also producers. some use light but most use chemical reactions to get their energy.

Consumers

All animals are consumers. They cannot make their own food so they have to eat or consumer it.

Primary consumers are herbivores.

A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material.

Secondary consumers are carnivores. They eat herbivores.

A carnivore /ˈkɑrnɪvɔər/ meaning 'meat eater' (Latin, caro meaning 'meat' or 'flesh' and vorare meaning 'to devour') is an organism that derives its energy and nutrient requirements from a diet consisting mainly or exclusively of animal tissue, whether through predation or scavenging.


Tertiary consumers are small carnivores that eat secondary consumers. They are sometimes called top carnivores.

Decomposers are microbes that feed on dead and decaying material. Most of these are bacteria and fungi. The decomposers turn the dead and decaying material into nutrients that the producers use to produce food.

Most bears are omnivores

Omnivores are animals that eat a mixture of plant and animal foods. some omnivores eat plants most of the time.

Animals Live in Different Places

Animals Live in Different Places

These factors vary in different places and can change from season to season.

• Amount of light
• Temperature
• Height above sea level
•  Oxygen and Carbon Dioxide
• Vegetation
• Moisture

Climatic regions of the world include arctic, desert, or tropical.

Arctic and Antarctic

 Arctic(North Pole) and Antarctic(South Pole) - There are freezing conditions all the year round, so the ground is frozen. There is snow in the long winters, summers are short. Plants are mostly low growing, like lichen and mosses. animals that live in this environment include penguins, seals, whales, fish, and polar bears. Some of these animals have thick fur or layers of fat called blubber to keep them warm.

Desert Regions

Desert Regions - It is very hot during the day and very cold at night. It is also very dry-less than 25 millimeters of rain per year. Camel is adapted to live in desert regions. A camel stores fat in its hump and can drink 40 gallons of water at one time. It does not sweat below 46C. Fur isolates its body from cold and heat , its large feet do not sink into the sand.

Tropical Regions

Tropical regions are hot and wet all the time. They contain the highest and most varied number of species on Earth. Conditions are ideal for growth the year round. The sun is directly overhead and there are no seasons.

The temperature is between 20C and 30C and the rainfall is about 2000 millimeters per year. The Tropical regions are covered in rainforests.

Arachnids Facts

Arachnids Facts

Arachnids is a term for animals that include scorpions, spiders, mites and ticks and certain others eight-legged land invertebrates.

All arachnids have:
- A body divided into two parts.
- Four pairs of legs.
- No antennae, but they can paralyses their prey with poison fangs.

Insects The Largest Group of Animal

Insects The Largest Group of Animal

Insects are the biggest group of animals, they are found all over the world, even in frozen lands and in very hot deserts where other animals find it hard to live. Most insects live on their own, but some live in organized communities.

- A protective outer covering called on exoskeleton insects are invertebrates, which means they do not have a backbone.
- A head which carries the eyes, antennae and the feeding parts.
- A thorax that carriers 6 legs and sometimes wings.
- An abdomen, made up of a series of segments. Vital organs like the heart are in yhe abdomen.
- Three pairs of jointed legs.
- Cold Blood - They cannot control their body temperature.
- Many have compound eyes, made up of hundreds of tiny lenses.
Some insects go through a change of body appearance called metamorphosis, which involves four stages. Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation.

Bees and Ants live in large groups. They work together to build a hive. Each insect has a special job to do. Some build, some collect food, some clean, and some look after the babies.

Grasshoppers are insects that have strong hind legs for jumping. They rub parts of their bodies together to make a singing sound to attract of mate. Their ears are on their knees.
