Parts of a plant
Embryo, stem, roots, leaves, seed coat
Asexually
Advantages
Not having to spend energy searching for mate. Also Populations increase rapidly and can exploit suitable habitat
Disadvantages
Sexually
No genetic variation makes them vulnerable to sudden climate changes and if a predator or disease adapts to kill one individual all are susceptible
Two parents are involved that contribute half of of the offspring's genetic information
Comes from a single parent and offspring is genetically identical
Polyatomic ions
Nitrogen cycle
Nitrifying bacteria
Nitrite( NO-2)
Nitrate (NO-3)
Uneven number of protons and electrons
Ecology
Nutrients
Salmon Loop Cycle
From salmon to trees
Salmon Carcass
Scavengers feed on
Scavengers feces deposited in forest
Scavengers hauls carcass into forest
Marine- derived nutrients enter soil
Nutrients taken up by vegetation through roots
Herbivores feed on vegetation
Covalent
- warmth, moisture, rich soil, good quality seed, sunlight
Nitrogen
Found in atmosphere, living creatures, soil, oceans and marine sediment
It is need for living organisms for DNA, proteins, chlorophyll in plants

Takes up 78% of Earth's atomsphere
Humans need six main elements to stay healthy( carbon, hydrogen, oxygen, nitrogen, phosphorus, calcium)
Plants need NPK ratio to gain nutrients
Used to construct carbohydrates, nucleic acids, DNA/ RNA, proteins
Example NO-3
1:3 ratio of oxygen and nitrogen
they share electrons
Nitrogen FIxing Bacteria
Nitrogen gas
Ammonium
Consumers eat plants to obtain nitrogen and plants absorb forms of nitrogen in the soil
Male and female gametes are produced from flowers
