PLANTS
What do Plants Need to
Grow?
Plants
need soil. Water and minerals are taken from the soil through roots. Soil also
provides support for the plant and an anchor for the roots to grow in. Decaying
plants and animals leave behind minerals in the soil that are essential for
future plant growth.
Plants
need sunlight in order to grow properly. They use light energy to change the
materials - carbon dioxide and water into food substances (sugars). This
process of food productions is called photosynthesis. Only in light can a green
plant make food.
Plants most also have clean
air. Green plants take in carbon dioxide from air and use it during
photosynthesis to make food. Dirty, smoggy air blocks sunlight that plants must
have.
Plants
need water. Water is essential to all life on earth. No known organism can
exist without water. Plants use water to carry moisture and nutrients from the
roots to he leaves and food from the leaves back down to the roots.
Plants are organisms that grow and reproduce their own kind. The need for, air, soil, water, light, and space to grow.Plants are essential for any ecosystem. They provide all the energy for the ecosystem, because they can get energy directly from sunlight. They use a process called photosynthesis to use energy from the sun to grow and reproduce. They also must get nutrients from the soil. Those nutrients get into the soil when decomposer break down waste and dead materials. Plants require space to grow and reproduce. The size of your ecodome will influence how much space your plants have.
All other organisms in the food chain get energy from plants, either by directly eating them as herbivor do, or by eating plant eaters, like carnivores do. Omnivores can get energy either by eating plants directly or by eating herbivores. Likewise, decomposers get energy either from plants or from the animals that eat them. Since all the energy in your ecosystem comes from plants, you'd better have a lot of them.
There are several different kinds of plants, and not all animals can eat all kinds of plants.
