Basic Needs of Plants

Plants need sunlight to stay alive. they also need air to stay alive. Without air, plants will die. Plants absorb water from the soil through their roots. They will wilt and die if they do not get enough water.








Plants were observed to grow when their basic needs were satisfied. When some of these needs were removed, the plants began to look sick and die. All living organisms must meet their basic needs or they will not be healthy.

Every organism needs to obtain energy in order to live. For example, plants get energy from the sun, some animals eat plants, and some animals eat other animals.

A food chain is the sequence of who eats whom in a biological community (an ecosystem) to obtain nutrition. A food chain starts with the primary energy source, usually the sun or boiling-hot deep sea vents. The next link in the chain is an organism that make its own food from the primary energy source -- an example is photosynthetic plants that make their own food from sunlight (using a process called photosynthesis) and chemosynthetic bacteria that make their food energy from chemicals in hydrothermal vents. These are called autotrophs or primary producers. 

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 are organisms that grow and reproduce their own kind. The need for, air, soil, water, light, and space 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. 

Water acts as the solvent for the minerals present in the soil and with the absorption of water from the soil minerals also enters the plant body. While these minerals could not be easily and naturally taken up by the plants if they were in solid state.

 

Plants needs enough space to stay alive.That depends greatly on the type of plant as there is huge variation between mature sizes. In general, find out the mature spread of the plant and allow for the spread of surrounding plants. 

Also take into account the rainfall and other requirements of the plant. You may have to increase the distance if the requirements are scarce in your area. See the link below for a sites that gives information about the size of many plants.

Plants are the only organisms that can convert light energy from the sun into food.  And plants produce ALL of the food that animals, including people, eat.  Even meat.  The animals that give us meat, such as chickens and cows, eat grass, oats, corn, or some other plants.
