b. grass growth increases
c. soil quality decreases
d. invertebrate variety decreases
Answers
The correct answer is grass growth increase.
The wildfire in the grassland can help to improve the soil quality there. There are many positive sides of the wildfires. One of them is that it helps to improve the soil quality and favors the growth of plants there.
As the area is grassland, there will be growth of the grasses.
In case of wildfires, the contaminated soil gets burned and the harmful microorganisms die due to the fire and this improves the quality of the soil which ultimately grows the grass.

Answer:
Air pollution
Explanation:
Pollution is the release of substances into an environment above a level that it becomes harmful to the organisms living in such environment. Pollution can occur both in aquatic and terrestrial environment. Pollution in the terrestrial environment can either be in the soil or in the air.
Burning of wastes leads to the release of smoke into the atmosphere. Smoke from waste burning consist of particulate matters, water vapour and varying levels of carbon doxide, carbon monoxide, oxides of nitrogen, oxides of sulphur, etc., depending on the content of the waste. These components have both short and accumulative long term effects on the environment. The effects include;
- smog
- global warming
- ozone layer depletion
- acid rain
- and so on.
In an ecosystem when waste is burnt it emits out pollutants which are released in air thus causing air pollution.
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.When waste is burnt, it gives out pollutants in the air thus causing air pollution.
Hence, the problem which is most directly caused by burning waste is air pollution.

Phosphorus cycles between living things and the SOIL
Explanation:
Phosphorus flows in a cycle within rocks, water, soil and sediments, and organisms. The phosphorus cycle is the biogeochemical cycle that represents the action of phosphorus within the lithosphere, hydrosphere, and biosphere. Phosphorus is an essential element for all sorts of life. As phosphate (PO4), it delivers up an essential part of the structural core that holds DNA and RNA mutually.
