Give at least three examples of key ecosystem services that nature provides for people.

To give: At least three examples of the ecosystem services that nature offers for the people.
Introduction: The important ecosystem services include the study of various species of organisms called genetic diversity. The second service includes the analysis of genotypic and phenotypic diversities in the animals, organisms, and insects found in the natural habitat like forests. The third key service includes the study of environmental diversity.
Explanation of Solution
The diversity of animals, plants, and insects is diverse. The role of animals is important in maintaining the equilibrium of the ecosystem and the natural habitat. The skin and fur of animals are important source of thermal regulation in organisms. The animal, plant, and insect products have aesthetic value in the cosmetic and beauty industry. Various plant products have medicinal value and are used for curing various diseases in the human body. The agricultural plants help in providing nutrition to humans in the form of food and fruits. The environmental diversity helps in studying the balance of nutrient cycles like carbon, oxygen, and nitrogen.
The advantages of key ecosystem services are as follows:
- Agricultural productivity increases due to crop rotation and nitrogen fixation in the soil.
- The food yield of the plant increases due to the method of hybridization.
- The higher and better varieties of animals provide milk and dairy products that are beneficial for the health of humans.
- Animal rearing and husbandry are helpful in agriculture.
- The yield of insects like lac and other secretions have aesthetic, beauty, and cosmetic values.
- Important experiments in animals help in the study of the effect of drugs.
A proper utilization of the natural resources with genetic, species, and environmental diversities are important for maintaining and conserving the environment. The cutting of trees, pollution, and the release of harmful chemical alter the climate leading to global warming. The balance of the ecosystem is important to prevent the extinction of plant and animal species.

Color the line that represents all ancestors of the Eastern white pine tree green (but only the ancestral line NOT shared with other organisms) 2. Oncle the last common ancestor of the Colorado blue spruce tree and Eastern white pine tree. 3. Put a box around the last common ancestor of the sugar maple tree and the dogwood tree. 4. Put a triangle around the last common ancestor of the red pine tree and the american holly bush. 5. Color the line that represents all ancestors of the Ponderosa pine tree red (including all shared ancestors). 6. Color the line that represents all ancestors of the American elm tree blue (including all shared ancestors). 7 Color the line that represents all ancestors of the Sabal palm tree purple (including all shared ancestors) 8. Using a yellow highlighter or colored pencil, circle the clade that includes all pine trees. 9. Using a orange highlighter or colored pencil, circle the clade that includes all gymnosperms 10. Can you tell…arrow_forwardYou have been hired as a public relations specialist to give invertebrates a good name. After all, they are much more than just creepy crawly bugs! Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward

How autosomal inheritance works. Compare the normal and mutated gene sequences simply. → Talk about possible consequences of a faulty hydrolytic enzyme.arrow_forwardCan you fill out those termsarrow_forward

Sucralfate comes as a 1 gm tablet, famotidine as 20 mg tablets, and doxycycline as 100mg tablets. All are in bottles of 100 tablets.How many total mg are needed for the patient and how many tablets of each would be needed to provide each dose?How many bottles of each would be needed to have available if this patient were to be on this drug regimen for 5 days?arrow_forwardThe patient needs a solution of 2.5% dextrose in Lactated Ringer’s solution to run at 75 ml/hr for at least the next 12hours. LRS comes in fluid bags of 500 ml, 1 Liter, 3 Liters and 5 Liters. How can a 2.5% solution be made by adding50% dextrose to the LRS?arrow_forward
