Chromosomes and Genes Every organism inherits traits from their parents. These traits can include how something looks, how it acts, and how likely it is to get certain diseases. The storage location for these traits are the genes. These are passed from the parent to the child. For example, if

Ecosystems Ecosystems are dynamic, which means that they change over time, either for the better or worse. These systems can often times experience disruptions in either the living or non-living parts of the system. Every change can affect the populations of the system. * A change can impact the populations negatively,

Photosynthesis in Ecosystems Energy from the sun is converted into chemical energy by plants through the process of photosynthesis. Plants take water from the ground, C02 from the air, and energy from the sun's rays to preform photosynthesis. After preforming photosynthesis, the plants release Oxygen, which is then

The Food Web In the image below, I have drawn a food web for the Arctic. The producers are eaten by the primary consumers (portrayed by a green line). The primary consumers' are food for the secondary consumers (shown by red arrows). Some secondary consumers eat each other (shown
Biology
Populations, Communities, and Ecosystems Populations are species in a community. Communities are groups of species that live together. Ecosystems are communities and non-living things in an area. In this image, we can see many populations represented, like the horse population, the llama population, the cow population, the pig population, the

Every animal and plant needs food for energy. Plants get food by making it themselves, but humans and animals have to find food. Food is used in the human body as both energy and building blocks. Large molecules of food that contain mostly oxygen, hydrogen, and carbon are broken down
Biology
Photosynthesis is the process by which an organism makes its own food. Some organisms that can do this are algae and plants. The main factor in photosynthesis is sunlight. The other two components of photosynthesis are water and carbon dioxide. The energy from the sunlight is used to break down
Biology
The more surviving offspring that a plant has, the more reproductive success it has. Certain things that animals do affect the reproductive success of plants. One of these is called pollination. This is when an animal takes some pollen from one plant to another, giving pollen from male parts of

Every organism's growth is directly related to the environment it grows up in and the genes that it has. The environment an organism grows up in affects how it grows. For example, a cat living in a house and being fed will be more healthy than a stray

The skeletal system is the backbone (literally) of the entire body. It gives our bodies the shape that they have, it stores minerals, it helps us move, it protects our organs, and it produces blood cells. There are six main parts of the skeletal system: * Bones are the part of

The digestive system is the system in our bodies that helps us consume what is good in food and get rid of the rest. This system is made up of ten organs: * The mouth is used for chewing food and softening it down with saliva. The saliva starts the digestion

The nervous system helps all animals and humans feel, see, and taste the world around them. The nervous system is made of a few organs: * The Brain is at the top of the body in the head. It receives information from all the nerves that tell it about the environment
