carnivore
Animals
26
Omnivore
Plants and animals
27
Predator
Animals (prey)
28
Scavenger
Already dead animals
29
Decomposer
Breaks down dead organisms and eats their waist
30
Radiant energy
Travel directly from the sun
31
Thermal energy
Present during heating and cooling
32
Light Energy
Visible forms of radiant energy
33
What creates glucose or thermal energy from light energy
Producer
34
Photosynthesis formula
Carbon dioxide + water + energy = sugar + oxygen
35
Reactants and product of photosynthesis
Reactant = Carbon + water Products = Sugar + oxygen
36
What happens to the light energy in the process of photosynthesis
Light energy is converted to chemical energy which can later be used by a plant
37
cellular respiration formula
Sugar + Oxygen = water + carbon dioxide + energy
38
Reactants and products of cellular respiration
Reactants = sugar, oxgyen Products = water, carbon Dioxide, Energy
39
Trophic level
Starting with producers ending with consumers
40
Atmosphere
Leather of gases surrounding the Earth
40
Arrows in a food chain represents what ?
Shows how energy is being passed along
41
Lithosphere
Earth solid Outer layer
42
Hydrosphere
All the earths water in solid, liquid, and gas form
43
Biosphere
The zone around the earth where life can exist
44
Lithosphere
The rocky outer shell of the Earth. (rocks, minerals, mountains, earth’s crust and mantle, etc.)
45
Photosynthesis Reactants Products:
Reactants: Sugar and oxygen Products: Carbon dioxide, water , energy
46
Complementary processes:
Photosynthesis and cellular respiration are complementary processes because the products of one reaction are the reactants of the other reaction.
47
What is the particle theory of matter?
It is a way to describe the structure of matter and how it behaves.
48
Pure substance vs Mixture
Pure substance: 1 type of particle Mixture: 2 or more different types of particles
49
Elements vs. Compounds:
Elements: A pure substance that cannot be broken down into simpler substances. ( hydrogen, sodium, oxygen, chlorine etc.) Compounds: A pure substance that contains 2 or more different elements in a fixed ratio. ( salt, sugar, water, carbon dioxide etc.)
50
Homogeneous vs Heterogeneous mixture:
Homogeneous: solution– different substances are NOT visible Ex. salt water, sugar water. Heterogeneous: mechanical mixture– different substances ARE visible. Ex. Rock and water, sand and stones.
51
Physical change:
A change in a substance that does not produce a new substance, even though it may change state, shape or form.
52
Physical property:
Characteristic or feature of a substance.
53
Qualitative physical properties:
Colour State Clarity Odour Taste Texture Lusture Malleability Flexibility Ductility
54
Quantitative physical properties:
Melting point Boiling point Solubility Hardness Electrical conductivity Viscosity Density Adhesion Cohesion
55
Chemical properties
The ability of a substance to react and form a new substance. Combustibility Reactivity with water Toxicity Stability
56
3 types of galaxies:
Barred Spiral Galaxy Elliptical Galaxy Irregular Galaxy
57
What type of galaxy is the milky way?
Barred Spiral Galaxy.
58
8 planets in order:
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
59
Inner vs. Outer solar system:
Inner= rocky/ terrestrial planets (Mercury, Venus, Earth, Mars) Outer= gas giant planets (Jupitar, Saturn, Uranus, Neptune)
60
What separates the inner and outer planets?
Between mars and jupiter is an asteroid belt which is a region of rocky debris that forms a ring around the sun.
61
Light year
Distance light travels in a year.
62
Why use light years?
Space is so huge so the use of kilometers would be impractical so we measure distances in space using light years.
63
Rotation
An object’s spinning around its own axis. 24 hours
64
Axis
An imaginary line that the object rotates around
65
Revolution
An object is circling around another object. a year
66
Orbit
A regular, repeating path that one object in space takes around another one. ( elliptical – oval shape)
67
Latitude
Horizontal parallel lines
68
degrees earth is tilted
23.5
69
The amount of sunlight we receive IS
what causes the climate changes during the seasons.
