Parts of a plant Screen Shot 2018-12-11 at 7.36.50 PM

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

Nitrifying bacteria

Nitrite( NO-2)

Nitrate (NO-3)

Uneven number of protons and electrons

Salmon Loop CycleScreen Shot 2018-12-11 at 9.19.13 PM

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) Screen Shot 2018-12-11 at 10.15.39 PM

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
