select the statement(s) that accurately predicts the impact of desertification on the ecosystem and food web.
desertification will cause flooding and loss of plant cover.
desertification will give farmers an empty place to plant and produce crops.
desertification has no major impact on food webs and ecosystems.
desertification will cause the loss of fertile land and, in turn, the loss of food production.
desertification will cause loss of the soil food web and the plant life it supports.

Explanation:

Desertification is the process by which fertile land becomes desert, typically as a result of drought, deforestation, or inappropriate agriculture. Let's analyze each statement:

• "Desertification will cause flooding and loss of plant cover": Desertification is more associated with aridity rather than flooding. Loss of plant cover can be a cause or consequence in some cases but flooding is not a typical impact.
• "Desertification will give farmers an empty place to plant and produce crops": Desertified land is not fertile for crop - planting.
• "Desertification has no major impact on food webs and ecosystems": This is incorrect as desertification disrupts habitats, reduces biodiversity, and affects food webs.
• "Desertification will cause the loss of fertile land and, in turn, the loss of food production": As desertification makes land less fertile, it reduces the ability to grow crops, leading to loss of food production.
• "Desertification will cause loss of the soil food web and the plant life it supports": The soil food web (consisting of microorganisms, insects, etc. in the soil) is disrupted when the soil becomes degraded (a part of desertification), and this in turn affects plant life.

Answer:

Desertification will cause the loss of fertile land and, in turn, the loss of food production.
Desertification will cause loss of the soil food web and the plant life it supports.
