Solar radiation travels through the earth's atmosphere and warms the planet's surface. greenhouse gases like carbon dioxide in the earth's atmosphere reabsorb the heat and warm the planet. the amounts of greenhouse gases have been increasing over the past century, causing the earth's surface temperature to increase. this gradual temperature change is thought to have many negative environmental consequences. which of these might be a positive effect of the increase in carbon dioxide levels? a) rise in sea levels b) decrease in plant growth c) increase in plant growth d) increased melting of ice caps

answer: c

explanation:

wild parsnip is a perennial plant which reproduces rapidly in areas which have no sign of agricultural activity such roadside or at no tillage open areas. it's considered invasive because it can inhibit the growth of another plant  and its reproduction is fast. there are several harmful effects of this invasive plant although its taproot is edible since it is a member of the carrot family. wild parsnips can cause skin blistering when in contact because of the chemicals it contains, second it inhibits the growth of other plants, it will restrict the growth of animals when eaten and lastly, it drives away natural pollinators like bees.
