Factors that change the ecosystems are called drivers.
There are direct and indirect drivers.
Direct drivers straightforwardly influence ecosystem process.
Indirect drivers operate more diffusely, By altering one or more direct drivers.
Some direct drivers:
Habitat change Climate change Pollution Invasive speciesOverexploitationSome indirect drivers:

Answer:water erodes the earth by passing over rock and thinngs many times, as in a river, the water slowly washes away the rock turning it into sediment or silt.
Explanation:
Answer:Hope this helps :) if so pleas could you mark brainliest:) enjoy!
Explanation:
The cycle of water erosion has been here since forever thanks to the rain rivers, ponds lakes, the sea and the ocean because it first starts off with the rain then the rain fills up the lakes and pond and start rivers and the rivers lead to the sea and ocean and from there the water evaperates then it rains again and the lakes and ponds help with the evaporation.
1.Where do the genes that determine an individual's traits come from?
, An individual can be born with any genes, since genes are random.
B.Individuals grow genes specific to their environment.
C.Parents pass their genes down to their offspring.
D.Parents choose which genes their offspring have when each individual is born
2.How do genes determine an individual's traits
A.Genes directly lead to traits
B.Genes are random and don't lead to traits
C.Genes give organisms the ability to change their traits
D.Genes are instructions for making protein molecules and protein molecules determine traits
Answer:
1. C
2. D
Explanation:
Parents pass down genes to there kids. They can pass down certain ones, like a gene for red hair.
Not every gene you get is instantly going to happen, if you get one brown hair gene and one red hair gene, you are going to have brown hair since it is a dominant trait.
Answer:
1) C. Parents pass their genes down to their offspring.
2) A. Genes directly lead to traits

The following table shows the distance from the sun of some unknown planets of equal mass.
W 1.5 AU
X 0.723 AU
Which of the following best explains which planet revolves at a faster speed?
A.) Planet X, because the sun pulls it with a greater force.
B.) Planet W, because the sun pulls it with a greater force.
C.) Planet W, because the gravitational force is weakened by distance.
D.) Planet X, because the gravitational force is strengthened by distance.
Answer:
Option D.) Planet X, because the gravitational force is strengthened by distance.
Explanation:
As we know from Kepler's law , the planets that are closer to the sun move at a faster rate in comparison to those planets that are far because of high gravitational force.
According to the question,
both planets have equal mass. Plant W is at 1.5 AU and planet X is at 0.723 AU distance from the sun.
So, planet X revolves at a faster speed because it's shorter distance from the sum as comparison to planet W, strengthened the gravitational field.
Thus, Option D is the correct answer.

Write a paragraph (5-8 complete sentences) answering the prompt＂How does the availability of resources in ecosystems impact ecosystems?＂
5-8 Sentences on: "How Does The Availability Of Resources In Ecosystems Impact Ecosystems?"
Changing out natural resources in our environment can affect the whole entire ecosystem. Ecosystems can change throughout time but the change may or may not affect the ecosystems. But according to research, if the change is too fast the whole ecosystem can be destroyed. An imbalanced or damaged ecosystem can lead to problems. Certain resources play an important role such as sunlight and water, we need resources to survive and can also help living creatures. These resources impact animals, plants, and insects/bugs.
P.S If you need more sentences I will edit my answer!

What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
