Nutrients
All organisms must take matter from their enviroment to survive. That matter is called nutrients. There are 92 naturally occuring nutrients on earth and livving things only need a minority of those.
Essential Nutrients for Humans
Humans need around 20 different elements to be healthy. Most mass from the human body comes from these 6 elements; Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus, Calcium
Those 6 elements;
Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus and Calcium
are used to construct the
Carbohydrates, Nucleic acids (DNA, RNA), Proteins
and other molecules that make up our cells and carry out their chemistry
Essential Nutrients for Plants
Plants carry out thousands of chemical reactions simular to humans. Plants have around 17 different elements essential for them. They absorb most of their essential elements from the soil. The elements are usually taken up as positively charged catio or a negatively charged anion
The three key nutrients for plants are Nitrogen (N), Phosphorus (P) and Potassium (K) . Comercially available fertilizers are labled with the proportions of each nutirents labeled as NPK Ratio
Lack of any of these nutrients will lead to nutrient deficiency
Nitrogen
Nitrogen is important to living organisms because it's needed for
DNA, Protiens, Chlorophyll in plants
Usable forms of Nitrogen are Nitrite, Nitrate and Ammonium
Fish Fertilizer
NPK Ratio
Nitrogen(N), Phosphorus (P), and potassium (K)
Polyatomic Ions
Polyatomic ions translate to "Many atom ions". They
(are or have not sure)
covalent bonds with a charge and can form ionic compounds with opposite charge.

Sexual Plant Reproduction
Flower and seed reproduction
Seed
A seed is an embryo covered in a seed coat
Legumes are seeds. Examples of types of seeds include quinoa, peanuts and coffee beans.
Seeds are the product of sexual reproduction
To make a seed the flowers must be pollinated. Pollen from the male part of a flower travels to the female part of another flower where seeds are created

Flower
Flower is the reproductive part of a plant in sexual reproduction (both male and female
Gametes (pollen and ovules) are produced by flowers
Sexual reproduction involves two parents that eachcontribute hald of offsprings genetic information
Asexual Reproduction
Asexual Plant Reproduction
There are many different ways plants to be reproduced asexually. New plants can grow from a portion of the roots, stems or leaves from an existing plant
New plants are clones (genetically identicle copies of the parent plant
Asexual reproduction, offsprings come from a single parent and are genetically identical
Advantages:
Populations increase rapidly and can exploit suitable habitat quickly
No energy spent searching for a mate
Disadvantages
No genetic variation (Diversity) makes them vulnerable to sudden climate change
If a predator or disease adapts to kill one individual they are all susceptible (same traits = same weaknesses)
reproduction ensures that life exists beyond its present generation
Multicelluar eukaryotic organisms rely on cell division (reproduction) to grow larger by adding new cells

Nitrogen Cycle
Nitrofixation
Convergen ditogen gas into nitrogen gas that can be used by plants by bacteria called Rhizobia
Nitrofication
Convergen of ammonium into nitrate by converging ammonium into nitrite than into nitrate by the rhisobia bactera
Producers (Plants) obtain nitrogen by absorbing usable forms from the soil
Consumers obtain nitrogen by eating the plant to obtain nitrogen
