1. Crabgrass, 2. A tropical rainforest that has been clear-cut to create highways and farmland, 3. A botanist grafts together shoots from two different kinds of pea plants.
Explanation:
As the initial stage of the ecosystem is the growth of trees and the secondary stage of succession is shown by the growth of grasses like the crabgrass and the development of small grass-feeding organisms. Most of the biodiversity is found in the tropical rain forests of the world and these harbor large scale animal and plant diversity in the world thus called the evergreen forests of the world. A botanist in order to get genetic drift has to merge the shots of two different kinds of pes species to form a mutated one.1. Crabgrass, 2.

3. The answer is "B)ecosystems".
An ecosystem is an extensive community of living beings (plants, creatures and microorganisms) in a specific zone. The living and physical segments are connected together through supplement cycles and vitality streams. Ecosystems can be of any size, however for the most part they are specifically puts.
Ecosystem, the complex of living creatures, their physical condition, and every one of their interrelationships in a specific unit of space.
4. The answer is "B)cadmium dosage".
An abiotic factor is a non-living segment in the earth. This can be either a concoction or physical nearness. Abiotic factors fall into three essential classifications: climatic, edaphic and social. Climatic components incorporate stickiness, daylight and variables including the atmosphere. Edaphic alludes to soil conditions, so edaphic abiotic factors incorporate soil and topography of the land. Social variables incorporate how the land is being utilized and water assets in the territory.
5. The answer is "D)A tropical reef aquarium with many different types of fish and corals."
Community, additionally called biological community, in biology, an interfacing gathering of different species in a typical area. For instance, a woods of trees and undergrowth plants, occupied by creatures and established in soil containing microscopic organisms and growths, comprises a biological community.
The individuals from an animal types living in a given zone in the meantime establish a populace. Every one of the populaces living and interfacing inside a specific geographic territory make up an organic (or biotic) network. The living beings in a network together with their nonliving or abiotic condition make up an environment.
6. The answer is "B)Mutualistic".
Cleaner Shrimps and Moray Eels have a mutualistic relationship.
The cleaner shrimp clean parasites, bugs, green growths, and so on off of the eels, making them more sound – consequently, the shrimp get a free feast. Cleaner shrimp likewise clean different types of fish like groupers and pufferfish.
Eels will likewise get cleaned by different kinds of fish like gobies and wrasses. The cleaner shrimp have brilliantly shaded exoskeletons to tell their clients that they are not typical shrimp, since they would somehow or another be eaten.
7. The answer is "C)The spider lays eggs in the ear of the deer and the spiderlings eat the inner ear of the deer, sometimes causing deafness."
A parasitic relationship is one in which one life form, the parasite, lives off of another living being, the host, hurting it and conceivably causing demise. The parasite lives on or in the body of the host.
As a rule, despite the fact that parasites hurt their hosts, it is in the parasite's best advantage not to murder the host, since it depends on the host's body and body capacities, for example, absorption or blood dissemination, to live.
8. The answer is "A) community".
Community, additionally called biological community, in biology, an interfacing gathering of different species in a typical area. For instance, a woods of trees and undergrowth plants, occupied by creatures and established in soil containing microscopic organisms and growths, comprises a biological community.
9. The answer is "B)all the catfish in the pond".
In biology , the term species alludes to all life forms of a similar kind that are conceivably competent, under common conditions, of rearing and creating fertile offspring. The individuals from an animal types living in a given region in the meantime comprise a populace. Every one of the populaces living and connecting inside a specific geographic territory make up an organic (or biotic) network. The living life forms in a network together with their nonliving or abiotic condition make up an ecosystem.
10. The answer is "A)a decrease in rainfall".
An ecosystem relies upon the associations of the living and nonliving components in the framework. The living things in a biological community are called biotic factors. Living things incorporate plants, creatures, microscopic organisms, growths and that's just the beginning.
- The non living parts of an environment are called abiotic factors. In a biological system some abiotic factors are daylight, temperature atmospheric gases water and soil.
- A noteworthy difference among biotic and abiotic factors is that an adjustment in any of the abiotic factors impacts the biotic elements, yet changes in the biotic components don't really result in changes to the abiotic factors. For instance, a reduction in precipitation would influence the mice populace of a region by making it diminish.

Update on Question:
Question # 10 was missing options. I have put the complete question here:
The crops grown in a small Midwestern farming community are being destroyed by grasshoppers. The farmers have banded together and have decided to spray pesticides to reduce the grasshopper population. What is likely to happen in the future as a result of this spraying?
a decrease in the bird population
an increase in crops harvested
reduced quality of groundwater
an increase in the snake population
increased precipitation
Explanation:
Answer # 1:
Abiotic substances are devoid of life, and are not derived from living organisms. They include things like carbon dioxide, sunlight, temperature, water, soil, etc. They can be organic and inorganic. Abiotic substances have significant influence over an ecosystem.
Answer # 2:
Biodiversity is the variety of plant and animal life in a particular habitat. High biodiversity is important and desirable.
Answer # 3:
water, soil, air, dead organic matter
Answer # 4:
Predators play a role in balancing the earth's ecosystems
People's activities can improve the health of an ecosystem
The parts of an ecosystem depend on each other
Your neighborhood park is an ecosystem
Answer # 5:
True
Answer # 6:
dry and hot
dry and cold
receives less than ten inches (twenty-five cm) of rain per year
Answer # 7:
Much grassland has been converted to grow crops.
Many birds of the grasslands build their nests on the ground.
The soil is rich in nutrients.
Answer # 8:
Marine Ecosystem
Answer # 9:
soil erosion
increased pollution
water runoff
reduced precipitation
Answer # 10:
a decrease in the bird population
an increase in crops harvested
reduced quality of groundwater
Answer # 11:
The ecosystem can be affected by the presence of snakes. A sudden increase in the number of predators may cause shortage of herbivore animals, which in turn may result in lower pollination and eventually cause reduction in plant growth.
Answer # 12:
Tundra
Answer # 13:
Forest
