How does competition lead to resource partitioning?.
Answer:
It happens when competition drives natural selection because of animals niches overlap. This causes animals to die if they don't adapt. Those that adapt usually adapt with resource paritioning because it allows the type of species to live if they shared 2 types of certain parts of food.

Select the correct answer from each drop-down menu. the sun is the primary source of energy for ecosystems. the sun emits . when an organism obtains nutrients by feeding on other organisms in the ecosystem, energy is used and released. energy changes form, but it isn’t destroyed as it transforms. this scientific law is called the law of .
The scientific law of one organism feeding off other where energy is transferred from one form to another is known as the law of conservation of energy.
How the sun is the primary source of energy for ecosystems?Energy from the highest energy source that is sun is absorbed by plants to convert it into food (i.e a form of energy). plants are the only ones that can convert sunlight into another form of energy directly.
The animals and organisms that feed off of the plants take some part of this energy for their life cycles and then the animals that feed off of these animals again take some part of this energy and carry on with their life cycle, this is how energy from sun (highest source) is transferred to different organisms by Just changing form.
Thus, The scientific law of one organism feeding off other where energy is transferred.

8. Describe: Locate the Sun on the H-R diagram. How will the Sun's luminosity and
temperature change as it ages? How will these changes affect its position on the diagram?
Answer:
It will eventually become less bright and cooler.
Explanation:
Astronomers estimate that the Sun's luminosity will increase by about 6% every billion years. This increase might seem slight, but it will render Earth inhospitable to life in about 1.1 billion years. The planet will be too hot to support life.
The Sun is a weakly variable star, and its actual luminosity therefore fluctuates. The major fluctuation is the eleven-year solar cycle (sunspot cycle) that causes a quasi-periodic variation of about ±0.1%. Other variations over the last 200–300 years are thought to be much smaller than this.
Answer:
it will turn into a super giant then eventually turn into a white dwarf star

formations with a vast underground cave system. What is likely the cause of the underground cave system?
A) wind erosion
B) chemical weathering
physical-weathering
D) deposition and compaction
Answer:Its C
Explanation: i took the test trust me
physical-weathering is likely the cause of the underground cave system.
Rocks, minerals, and soils disintegrate through a process known as physical weathering, sometimes known as mechanical weathering.
Abrasion is the main physical weathering process (the process by which clasts and other particles are reduced in size). Temperature, pressure, frost, root movement, and burrowing animals can all cause physical weathering.
For instance, physical weathering will expose more surface area through the use of cracks, speeding up the pace of deterioration.

Explanation:
The weathering that most likely played the largest role in creating the cliff was when water in the river broke down the rocks into smaller pieces, which is present in Option B.
What is the weathering process?Rock cliffs can be formed by a variety of weathering processes. One common process is erosion caused by the movement of water as seen here as water flows through the mountains. Over time, these agents of erosion can wear away the softer layers of rock, leaving behind the harder layers that form the cliffs. Physical weathering is caused by the action of natural forces such as water, wind, etc. For example, water can flow into cracks in rock and then freeze and expand when the temperature drops, causing the rock to break apart. Wind can also erode rock surfaces over time by carrying small particles of sand and other debris that scrape and wear down the rock.
Hence, here the largest role in creating the cliff was when water in the river broke down the rocks into smaller pieces, which is present in Option B.
