POOP LOOP LAB 
BIOLOGY
DEFINE: the study of living organisms, divided into many specialized fields that cover their morphology, physiology, anatomy, behavior, origin, and distribution.
NUTRIENTS
What are nutrients?
All organisms must take in matter from their environment in order to survive. There are 92 naturally occurring elements on Earth. Living things only need a minority of them. #
Humans require around 20 different elements to be healthy.
Almost all of the mass of human bodies comes from just six of those elements: Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus, Calcium.
These are the elements used to construct the carbohydrates, nucleic acids (DNA/RNA), proteins, and other molecules that make up our cells and carry out their chemistry.
In our plants lab, we are giving the plants fertilizer which contains lots of rich and vital nutrients to help a plant thrive.
Salmon
Salmon can provide a lot of vital nutrients for plants and animals. This is a cycle called the Poop Loop. # #

Asexual
Asexual reproduction: Offspring come form a single parent (ex. bacteria) and are genetically identical
Advantages:
-Populations increase rapidly and can exploit suitable habitat quickly.
-No energy spent or time spent searching for a mate.
Disadvantages:
-No genetic variation makes them vulnerable to sudden climate changes
-If a predator or disease adapts to kill one individual they are all susceptible.
Sexual
Sexual reproduction: Involves two parents that each contribute half of the offspring's genetic information (ex. Humans).

Seeds Are The Product of Sexual Reproduction
To make a seed a flower must be pollinated. Pollen from the male part of a flower travels to the female part of another flower where the seeds are made. Most, but not all plants, have both male and female parts inside one flower.
Seeds
-
What are some conditions necessary for the growth of a seed: Moisture, Warmth, Nutrient Rich Soil, Sunlight, Good Quality Seed
-
What are some important parts of plant as it is growing: Root, Stems
What is the definition for germination: The process of the growth of a seed into a plant #
Reproduction
What is reproduction?
Reproduction ensures that life exists beyond its present generation. The sustainability of living things depends on reproduction. Reproduction happens at the level of the organism and at the cellular level. All the life you see around you, all the life in the world beyond the places you live depends on the ability of cells to reproduce.

Multicellular eukaryotic organisms, including plants, animals, and fungi, rely on cell division (reproduction) to grow larger by adding new cells.
CHEMISTRY
DEFINE: the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.
There are 17 essential elements for plants. They absorb the essential elements from water in the soil. Usually the essential elements are taken up as positively charged cation or a negatively charged anion. #
-
Commercially available fertilizers are labeled with the proportions of each of these nutrients (NPK ratio). Lack of one or more nutrients is evident in plant growth as a nutrient deficiency.
These are the three key nutrients for plants: Nitrogen (N), Phosphorous (P), and Potassium (K).
Polyatomic Ions
Polyatomic Ions mean atom with many ion. They are composed of two or more atoms bonded together with covalent bonds with and uneven number of electrons and protons. They create a net charge.
When polyatomic ions form bonds with other ions of the opposite charge. Also an ionic compound with polyatomic ions are neutral.

Nitrogen is important to living organisms because it's needed for: DNA, proteins, Chlorophyll in plants
-
ECOLOGY
DEFINE: the branch of biology that deals with the relations of organisms to one another and to their physical surroundings.
Nitrogen Cycle
Salmon
They bring back the nitrogen from the ocean to the forest. This happens because when predators consume the salmon, they often leave their corpse in the woods. Then their carcass transfers rich traces of nitrogen and other marine nutrients into the soil.
78 percent of the earth's nitrogen is in the earth's atmosphere but that nitrogen cannot be used for plants and animals because it can't absorb nitrogen gas.
The nitrogen cycle is a series of events that turn nitrogen in the atmosphere into usable nitrogen that the plants can use from the soil. It is called nitrogen fixation and decomposition.
Consumers consume organisms to gain this nitrogen. # #
