What does it mean to be a "pioneer"? Using your explanation, what do you think it means if something is a "pioneer species"?

Answer:

to be one of the first people to do something:

a person who is among the first to study or develop something

Explanation:

Pioneer species are hardy species which are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by fire.[1] Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants

What causes the southern hemisphere to experience summer? A. Earth's north pole is tilted toward the Sun. B. Earth's axis and its equator are at different angles. C. Earth's axis and its orbit plane are at different angles. D. Earth's south pole is tilted toward the Sun.​

True

False

2.)Plants are not part of food chains.

True

False

3.)
Both currents and tides are predictable patterns of movement in water.

True

False

4.)
The main benefit of an upwelling is that it

creates strong tides in coastal regions

increases the salinity of the water in an area

brings new nutrients into an underwater region

wipes out entire ecosystems, allowing for secondary succession

5.)Which of the following is true of brackish water?

The salinity of the water can vary with the tides.

There is usually more fresh water than salt water.

Very few organisms can survive in brackish waters.

It is most common in the deepest region of the ocean.

6.)A high tide will occur

usually only once in a 24-hour period

only in bodies of water close to the moon

on both sides of the earth at the same time

when proximity to the sun makes the days longer

7. Brackish water is most commonly found in

seas

rivers

oceans

estuaries

8.)All of the following are characteristics of the blue crab EXCEPT

it has no natural predators

blue crabs often feed on each other

it can adapt to varying levels of salinity

it migrates to cooler temperatures as it ages

9.)Unusual weather can change the tides.

True

False

10.)Black sand can be found when

tides are particularly high

sediment contains volcanic ash

local residents prefer it to light sand

all the sand is washed away from the beach

11.)Which of the following is a benefit of inhabiting an estuary?

The water levels are consistent.

The salinity levels are usually stable.

There are fewer strong ocean currents.

Very few predators can survive in brackish water.

12.)All of the following can influence tides EXCEPT

winds

hurricanes

heavy rains

the shoreline

13.)All of the following influence tides EXCEPT

the sun

the moon

the air temperature

the rotation of the earth

14.)The organisms that can tolerate the most time out of water would live in the

spray zone

high-tide zone

middle-tide zone

True

False

Field mustard is an annual plant that grows wild in many regions of the world. It has small yellow flowers and is pollinated by insects. Field mustard has to flower and produce seeds to give rise to the next generation. Southern California experienced a severe drought between 2000 and 2004. Plants that flowered earlier reproduced. Those that flowered later died without producing seeds. This led to more early-flowering field mustard plants. This change in population characteristics took only a few generations.

How do you think scientists discovered that the flowering time of the field mustard had changed?
