The biosphere is the global sum of all ecosystems. Defined as the zone life on Earth. All of the microbes, plants, and animals can be found somewhere in the biosphere.


Biomes are defined as the world's major communities, classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment. Biomes can be classified as Aquatic, Dessert, Forest, Grass Land, Tundra.

a system formed by the interaction of a community of organisms with their environment. It is also, considered a community of living and non-living things that work together. Ecosystems living and non-living structure is determined by the number of equivalent environmental factors.

communities is defined as all the populations in a specific area or region at a certain time, A community is bound together by the network of influences that species have on one another. A population of species work with one another, They form biological communities. structures arise within communities as species interact, food chains,food webs, guilds and other interactive webs are created.

Populations are groups of individuals belonging to the same species that live in the same region at the same time.Populations change over time due to births, deaths, and the dispersal of individuals between separate populations.

An individual living thing that can react to stimuli, reproduce, grow, and maintain homeostasis. It can be a virus, bacteria, fungus, plant or a animal.

to be considered and organism they have to:

1) All living things are made up of cells.

2) All living things reproduce.

3) Living things respond to their environment.

4) Living things adapt to their environment.
5) Living things grow.
6) Living things consume energy

organ system

The human body is made up of several organ systems that work together as one unit. Some organs are The cardiovascular organs which make up the heart, blood vessels and blood. The Lymphatic organ which are lymph vessels, lymph nodes, thymus, spleen and tonsils. Primary organs which contain the mouth, stomach. intestines and rectum and many more.

An Organ is a grouping of tissues into a distinct structure, as a heart or kidney in animals or a leaf on a plants, that performs a specialized task. Our organs work with your other systems to keep your body healthy by transferring all the nutrients from the digestive system to the blood and your muscles to help you stay strong and have a balanced metabolism. organs also help you move and keep from getting sick by producing, white blood cells and red blood cells.

a group or mass of similar cells working together to perform certain common functions There are 4 major types of tissues Epithelial, Connective, Muscle, Nervous. Epithelial tissue is found throughout the body, covers all body surfaces both inside and out. Connective tissue is the most abundant tissue in your body, found throughout
and binds structures together. Muscle is Skeletal Smooth in hollow organs and stomach and Cardiac - wall of the heart. Lastly, Nervous tissue which is found in brain spinal cord and nerves.

All living organisms are divided into cells. The human body is made of trillions of cells. They provide structure for the body, take in nutrients from food convert those nutrients into energy, and carry out specialized functions. Cells have many parts, each with a different function, some parts are called organelles are specialized structures the perform certain tasks within a cell.

a specialized part of a cell having some specific function;a cell organ. some organelles are A nucleus is an organelle that contains the cells DNA. A ribosome is an organelle in which amino acids are hooked together to make amino acids and the golgi complex the organelle the processes, packages and transport material and other materials out of the cell

A molecule is a group of two or more atoms that stick together. Molecules are so small that nobody can see them, except with an electron microscope. Pretty much everything on Earth and other planets are made of molecules, ll molecules need some way to hold their atoms together. The two main ways that atoms hold together are covalent bonding and ionic bonding.

A Atom Is a basic unit of matter that has a dense central nucleus surrounded by a cloud of negative charged electrons. Atoms make up everyday objects, there are 90 naturally occurring types of atoms and scientist have only been able to find 25. If you wanted to build a molecule you would need different types of Atoms.
