Read the passage. Then, use what you know about how populations affect one another during ecological succession to explain what happens on an empty lot.
Imagine what happens in an empty lot that has been cleared of all living things. As in a garden that is no longer planted, only soil remains. Weeds begin to grow in the soil. At first, only plants that need full sun to sprout grow there. But over time, these plants grow taller and shade the ground. Then, a different kind of plant begins to grow there, one that grows only in shady areas. Eventually, the lot is covered in mostly plants that sprout in shade.

Lab: Interdependence of Organisms
Interdependence Of Organisms
Question Being Answered:
How can the presence of one species benefit another in the same ecosystem?
Hypothesis:
If plants grow in soil that contains worms the plants growth will be greater because worms are able to help decompose organic matter and help distribute it through the soil in a form plants are able to use.
Process Of Lab:
In this lab you will grow two different groups of plants. Group A is considered the experimental group which will grow in soil with worms, Group B is considered the control group which will grow in soil without worms. After the plants grow you have to measure the plant growth for both groups and compare them.
Independent & Dependent
Independent Variable: Presence Of Worms
Dependent Variable: Plant Growth
Safety Procedure
Be sure to follow the safety procedure which means to
Wear safety goggles and lab gown while doing the experiment
Keep lab behavior purposeful
Look over the soil contents and make sure to follow warnings provided on any equipment
Wash hands and lab equipment once done with experiment
Treat living organisms with respect and provide proper care
Report any accidents that happen in the lab to your teacher
Lab Procedure
Step 1: Gather Materials
Two trays that are 10 cm 4’ deep
Potting soil
Lima bean seeds which need to be soaked overnight
Location with sunlight or growth lights
Worms
Graduated cylinder
Water
Black marker
Ruler with metric markings
Step 2: Prepare Two Trays Of Lima Bean Plants
Label the trays Control Group and Experimental Group
Add approximately 6-7 cm of soil to each tray
Plant 6 lima bean seeds in each tray being 2 cm deep and label the plants 1-6
Step 3: Give The Plants Water And Light During Sprouting Time
Keep the environments for both groups identical
Water all the plants following the watering schedule that was recommended on the seed packaging
Use the graduated cylinder to ensure the same amount of water is being given to both groups
Make sure all plants get the same amount of light
Step 4: Measure The Heights Of The Plants At The End Of Week 1
Measure the height of all twelve plants to the nearest cm. If a plant dies mark an x on the data table for that plant and write it in your notes
Use a calculator to find the average heights of the living plants in each groups
Calculate the difference in those average heights by subtracting the average height of the plants in the control group. Use this difference as a basis for comparison
Record measurement observations in your notes and the health of the plants such as leaf colors and size, wilting, unusual growth, brown spots, and any other marks you see
Step 5: Add Six Worms To The Soil Of The Experimental Group Of Plants
Write descriptive notes about the condition of the worms in your notes
Step 6: Measure The Heights Of The Plants At The End Of The Week 3
Repeat step 4
Step 7: Measure The Heights Of The Plants At The End Of Week 5
Repeat step 4
Step 8: Check The Health Of The Worms At The End Of The Study
Are the worms still alive?
Do they all seem healthy?
Have they changed in any way? If so list the ways changed
Are there any new worms
Be sure to write descriptive notes about their conditions in your notes
Step 9: Dispose Of All Material According To The Directions From Your Teacher

Describe the preservation principle of salting
Salting, especially of meat, is an ancient preservation technique. The salt draws out moisture and creates an environment inhospitable to bacteria. If salted in cold weather (so that the meat does not spoil while the salt has time to take effect), salted meat can last for years.☜(ﾟヮﾟ☜) (⌐■_■)
Why does the earth have different layers?
Answer:
The earth has different layers because as it formed, the lighter parts (like continental crust) floated to the surface, and the really heavy parts (like iron and nickel in the core) sank to the middle. It is just like when you mix oil and water: the oil will float to the surface because it is lighter (or less dense) than the water.

Explain how ocean temperatures affect the climate of coastal cities.
Answer:
Explanation: Warm ocean currents heat the air above the water and carry the warm air to the land, increasing the temperature of the coastal region. The same is true for cold ocean currents, except that they carry cooler air to the land and lower the temperatures of the coastal region.
Answer:
Warm and cold ocean currents can influence coastal climate, but only when local winds come in from the sea. Warm winds heat the air over the ocean, causing temperatures to rise over land. Cold currents will cool the air and add cooler temperatures to the land.

What is the difference between genetic drift and natural selection?
Genetic drift is the random increase or decrease of certain genes in a population; natural
selection is not random.
Genetic drift is the selection of random traits in a population; natural selection is the
selection of specific traits.
Genetic drift is the frequency of genes in a population; natural selectic is the frequency
of adaptations in a population.
Genetic drift is the change in a population's genes over time; natural selection is the
evolution of a population over time.
