Food Chain/ food Web
In this food chain the flower is a producer, the caterpillar is the primary consumer, the frog is the secondary consumer , the snake and the owl are de top consumer.
In this food web the green plant is a producer; the mouse, the rabbit, and the goat are the primary consumer. The snake, the owl, the wild cat, the jackal, and the lion are secondary consumer, The kite and the lion are top consumer.
Food Chains
Every living thing needs energy in order to live. Everytime animals do something
(run, jump) they use energy to do so. Animals get energy from the food they eat, and all living things get energy from
food. Plants use sunlight, water and nutrients to get energy (in a process
called photosynthesis). Energy is necessary for
living beings to grow. A food chain shows ho aclivg thg gets food, and how mutriets and energy are passed from creature to creature. Food chains begin with a plant-life, and end with animal- life. Some animals eat plants, some animals eat other animals.
Simple Food Chain
A simple food chain could start with grass, which is eaten by rabbits. Then the rabbits are eaten by foxes.
Bigger Food Chains
Here's another food chain, with a few more animals. It starts with acorns, which are eaten by mice. The mice are eaten by snakes, and then finally the snakes are eaten by hawks. At each link in the chain, energy is being transferred from one animal to another.
There can be even more links to any food chain. Here another animal is added.
It
goes grass to grasshopper to mouse to snake to hawk.
There is actually even more to this chain. After a hawk dies, fungi (like mushrooms) and other decomposers break down the dead hawk, and turn the remains of the hawk into nutrients, which are released into the soil. The nutrients (plus sun and water) then cause the grass to grow.
It's a full circle of life and energy!!
So food chains make a full circle, and energy is
passed from plant to animal to animal to decomposer and back to plant! There can
be many links in food chains but not TOO many. If there are too many links, then
the animal at the end would not get enough energy.
Decay/ Decompose
Youtube video by PBS Kids.
Fungi, plants, bacteria, and insects help dead organism decompose or decay.
Decomposers
Bacteria
and fungi are decomposers. They eat decaying matter - dead
plants and animals and in the process they break them down and decompose them
When that happens, they release nutrients and mineral salts back into the soil -
which then will be used by plants!
Consumers
Animals are called consumers. This is because they cannot make their own food,
so they need to consume (eat) plants and/or
animals.
There are 3 groups of consumers.   |
Producers
Plants are called producers. This is because they
produce their own food! They do this by using light
energy from the Sun, carbon dioxide from the air and water from the soil to
produce food - in the form of glucouse/sugar.
The process is called photosynthesis.
The process is called photosynthesis.

Stimulus
Stimulus is something that causes a reaction in a living thing.
When a turtle pull its head inside its shell, it is reacting to something it has heard, seen, or smelled in its environment.
Every behavior is caused by a stimulus.

the rabbit is running because it feel threatened.
The squirrel is climbing the tree because it feel threatened.
