Here is a picture of a white birch tree. All plants including trees have nonliving portion known as a xylem. The xylem helps transport xylem sap all the way from the plants roots to their leaves. This sap carries any nutrients and minerals the tree or any plant may need. The xylem sap is not carried through out the plant by gravity but by transpiration. Transpiration is when water is lost from the leaves their is a pulling force that brings the xylem sap from the roots through the shoot and to the leaves.
The beach sand pictured here resembles a heterogeneous mixture. Unlike a homogeneous mixture you can see all of the substances that create this mixture. If you look closely you can see all of the pebbles and rocks that combine to form what we all know and love, sand.
Here is the Cicada in the adult stage |
Here is a picture of a grasshopper. Grasshoppers are herbivores and are primary consumers. Herbivore meaning they eat the producers and primary consumer meaning they are on the second level of the food web. Their main diet consists of grass and leaves. Because they only eat the plants they are primary consumers where as the secondary consumers will not only feast on the plants but other organisms as well.
This seaweed I found in the ocean is a producer. Producers are at the bottom of the food chain, they use the suns energy to crate their own food, sugar.Plants are the only organisms that can produce their own food because of a special organelle in their cells known as the chloroplast.Animal cells do not contain a chloroplast therefore relieing on plants and other organisms for their meal. For the process of photosynthesis to acquire a plant uses the chlorophyll produced in the chloroplast. Along with the chlorophyll plants use the suns energy, carbon dioxide and water in order to create the sugar.
Here is a picture of a dragonfly I found by a pond.These insects are classified as odonatas along with the damselflies.These insects have transparent wings as well as compound eyes. They have small bodies and even though they have six legs they cannot walk. Because of the dragonflies compound eyes they have great vision. There eyes are constructed with many optical lenses known as ommatidia. These lenses are light sensitive allowing the dragonflies to see colors that humans could not see including ultraviolet lights.

Katelin, nice variety of items. The frost flower is really cool. I also like that you included the cicadas, this being a big year for many of those organisms.
