Interactions and Ecosystems
The study of relationships between living things and their environment.
What is Ecology.
Plants have been used to provide humans with a variety of resources. What are three ways in which humans have used plants over the years.
Possible answers:
1) Plants for clothing
2) Plants for food/shelter
3) Plants for fuel/transportation
4) Plants for medicine
What is:
1) All substances are made of tiny particles too small to be seen.
2) All particles are always in motion.
3) The particles have spaces between them.
4) The motion of particles increases when temperature increases.
What is:
1) mass structure
2) frame structure
3) Shell structure
The ways in which we can identify a mineral.
What is:
1) color
2) Lustre
3) Streak
4) Cleavage/Fracture
Occurs when two species live closely together in a relationship that lasts over time. Name the three types.
Symbiosis.
1) Mutualism
2) Commensalism
3) Parasitism
The tendency of particles in a gas or a liquid to become evenly distributed my moving from areas of high concentration to areas of low concentration.
What is diffusion.
1) weight-measured in newtons-scale
2) mass-measured in g/kg-balance
What is:
1) Igneous rock
2) Sedimentary rock
3) Metamorphic rock
The different kinds of monitoring practices to check the health of an ecosystem. There are 4.
What are:
1) Physical
2) Environmental
3) Chemical
4) Biological
Two ways in which plants produce. Describe each one.
What is sexual and asexual.
Sexual reproduction is when a plant uses seeds and fruits of specialised cells from two different plants.
Asexual reproduction (vegetative reproduction) occurs when a 'parent plant grows new plants from its stem, roots or leaves.
An increase in temperature causes water particles to move faster. Some of those particles near the surface of the water gain enough energy to escape into the air, thereby cooling the substance.
What is evaporative cooling.
Internal forces are exerted from a structure within. Name the 4 types and explain each.
What is:
1) Tension
2) Shear
3) Compression
4) Torsion
Name the different types of weathering and give an example for each.
1) Mechanical weathering
2) Chemical weathering
3) Biological weathering
The roles an organism plays in the environment. List all five of them.
What is an organism's niche.
1) Producers
2) Consumers
3) Herbivore
4) Omnivore
5) Carnivore
During the day, the plant uses carbon dioxide and water. When there is no light, the plant releases carbon dioxide and takes in oxygen.
What is respiration.
1) Conduction
2) Convection
3) Radiation
Name at least 3 types of rigid joints and give an example for each.
1) Ties
2) Fasteners
3) Adhesives
4) Interlocking shapes
5) Melting
The Earth is separated into different layers. Name the layers in order from top to bottom.
What is..
1) Crust
2) Upper mantle
3) Lower mantle
4) Outer core
5) Inner core

The last two processes called ___________ and _____________ return water to earth.
What is evaporation and transpiration.
What is condensation and precipitation.
Most flowers have male and female parts that are needed for reproduction. Name the female and male parts.
What is:
male: stamen
female: pistil

5/6) sublimation (gas-solid)
1) Find something solid
2) Make a solid layer
3) Spread the load
1) Normal fault (tension)
2) Reverse fault (compression)
3) Strike-slip/Transform fault (shear)
