42
Q

what is an example of energy? (food chain)

A

the sun because it helps provides the producer

43
Q

what is an example of a producer? (food chain)

A

the grass because it provides the primary consumer

44
Q

what is an example of a primary consumer? (food chain)

A

a grasshopper because it provides the secondary consumer these are animals that eat from (plants) producers

45
Q

what is an example of a secondary consumer? (food chain)

A

a bird because it provides for the tertiary consumer these are aminals that can eat the producers and primary consumer

46
Q

what is an example of the tertiary and or apex consumer? (food chain)

A

a fox these are animals that eat other animals and is eats producer, primary and secondary consumer?

47
Q

what is an apex Predator?

A

this is an animal is capable of eatting the secondary comsumer wich will turn the earlyre apex predator will turn into the tertiary that is at the top of the food chain as in a wolf

47
Q

what is a decomposer?

A

this is an organism, that often bacterium, fungus, and or invertebrate that will feed on and breaks down dead plants and or animals matter, that will make organic nutrients availably to the ecosystem.

47
Q

what dose FBI mean?

A

in the water or the water

50
Q

how far do you half to be to get the slope incline ‘ ?

A

you must stand 20m away from the water with a Clinometer

50
Q

how do you get the soil ph?

A

Moisten the soil with a few drops of Universal Indicator. Puff a little barium sulphate on the top of the soil in the container. Wait a few moments for the barium sulphate to absorb the colour. Compare the colour with the colour chart to find out the pH of the soil

51
Q

how do you get the water ph?

A

Moisten the soil with a few drops of Universal Indicator. Puff a little barium sulphate on the top of the water in the container. Wait a few moments for the barium sulphate to absorb the colour. Compare the colour with the colour chart to find out the pH of the water

59
Q

. What are tectonic plates

A

large slabs of rock that divide Earth’s crust

A

The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter

65
Q

explain how earthquakes form?

A

When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel

66

Q

what is chemical weathering?

A

acid rain

71
Q

what is biological weathering?

A

this is where plants grow in and under and above the rock dirt and other

72
Q

what is physical weathering?

A

this is the water frezzeing and t=doing over and over againg till the part of the rock falls off

73
Q

Where are how are sediments deposited

A

this is along or near a coastline by low-energy waves that can no longer support their sediment load
