What is the Cambium and the sapwood layers in the bark?

Cambium: Thin, yellowish layer, produce xylem cells every years allowing the tree to grow

Sapwood: water and nutrients are dissolved and transported here. surrounds the heartwood

Explain the water cycle with a plant

Plants need water to live, they lose water through transpiration, and take water up through their roots. 

All the water in an ecosystem is recycled, water goes into soil (precipitation), taken up by the tress, given off by trees (Transpiration), goes into the air as water vapor, condenses in the air and falls as precipitation. 

Cycles

100

What occurs in the upper canopy?

The top part of the forest that is like an umbrella covering the rest

200

The process by which trees make their own food is called

Photosynthesis

300

What is the nutrient cycle?

Begins with the food in the soil being absorbed by the tree roots, traveling up the trunk up the trunk to the leaves and then the leaves falling back down to the ground to be decomposed and put back in to the solid be the worms. food energy passes through the cycle over and over again in this order. 

400

In the water cycle precipitation comes down from the clouds, and lands back in the ocean. The next part of the cycle for this water would be? 

Evaporation

500

The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, ______    _______, leave the leaf. 

What leaves the leaf?

Sugar and Oxygen
