Producer
|
of an ecosystem is something that can use photosynthesis. They can take light energy using chlorophyll; will turn light energy into chemical energy. (Fats, sugars, proteins) This makes the plant very sufficient.
|
|
|
Heat
|
Every time energy is transferred from one organism to the next, some of the energy becomes useless. Each time it’s transferred from one producer to the next, energy is lost to heat.
|
|
|
What does the producer need?
|
Carbon Dioxide, Minerals (nitrogen, iron, phosphorus, magnesium)
|
|
|
Consumer
|
Anything that doesn't produce the energy
|
|
|
ATP
|
Humans consume chemical energy (atp).
Humans cannot store ATP we are constantly producing it. We do this by using ATP to break chemical bonds. |
|
|
Characteristics of a living Cell
|
1) Complex organization chemicals
2) Metabolism - obtain and use of energy. Adenosine triphosphate (ATP) Life can obtain energy and use it due to the chemistry inside the cell. |
|
|
Life can obtain energy and use it due to the chemistry inside the cell.
|
3) Response Controls
4) Growth/Development/Reproduction 5) Biological Information |
|
|
Two Types of Cells
|
1) Prokaryotic
2) Eukaryotic |
|
|
Ribosome
|
where our proteins are made
|
|
|
Organelles
|
small organ
|
|
|
Mitochondrion
|
where most energy is produced.
|
|
|
3 kingdoms of life
|
1) Archaeobacteria (Prokaryotes)
2) Eubacteria (prokaryotes) 3) Eukaryotes |
|
|
1) Archaeobacteria (Prokaryotes)
|
They are often found in hostile environment. Very salt content, heat content, acid content. 4 and a half billion years ago earth was made. 3 and half years ago life was born. Ancient cells. These were the first cells born on earth. Different biochemically and genetically.
|
|
|
2) Eubacteria (prokaryotes)
|
these are the true bacteria, the ones that we are more familiar with. They are fundamentally different from Archaeobacteria.
|
|
|
Which of the three types listed above demonstrates the virus?
fungiform, inverted, and cylindrical cell |
Fungiform
|
|
|
Elements
|
Cannot be broken down from natural means. 192 elements. What makes an element an element? You can have 1 atom of gold and it still be gold. 92 natural occurring (often found)
|
|
|
Atoms
|
difference of atoms is the different atomic mass, or amount of protons. Regardless of the amount of electron orbits going around the center of the atom. It’s the electrons in the outer layer orbit that determines its atomic make up. Protons are what determine the atom.
|
|
|
Water
|
A molecule composed of atoms, which is a part of an element.
|
|
|
Molecule
|
A group of two or more atoms held together by a covalent bond.
|
|
|
Search for life makes up what two characteristics
|
1) The presence of water
2) Carbon |
|
|
Proton
|
is very important; we assign it a positive charge. However many protons there are, is how many electrons there are.
|
|
|
Neutron
|
has no electric charge. Its mass is about the same as a proton. They also determine isotopes. You add protons and neutrons to get atomic mass.
|
|
|
Atomic mass
|
Protons + Neutrons
|
