How does animal agriculture impact the Great Barrier Reef? Select ALL correct optionsCarbon emissions that contribute to global warming increase, harming corals, e.g. bleaching.1Runoff can carry excess nutrients, causing algae to bloom and smother corals.2Animal agriculture has no effect on the Great Barrier Reef.3Land clearing can degrade soils, increasing runoff of sediment and animal waste.

How does water runoff from the land impact marine life? Select ALL correct optionsIf the land is polluted or cleared, more sediment and nutrients enter the ocean with runoff, harming reef species.1Increased runoff from cleared land then using it for livestock is beneficial to the reef.2Extra nutrients in the water helps the corals grow faster, allowing them to outcompete sponges.3Sediment and excess nutrients causes algae and sponges to smother corals.4

Damage to Ecosystems: Litter can smother coral reefs, seagrass beds, and other vital marine habitats, disrupting ecosystems and reducing biodiversity. It can also interfere with the natural behaviors and reproductive cycles of marine species.

How can fishing impact reef ecosystems and marine species?   Select ALL correct optionsFishing can create bycatch, killing non-target species like turtles.1Discarded nets, lines and hooks can entangle animals.2Taking organisms from the ocean does not harm marine species.3Fishing helps to keep the ocean clean by removing organic matter.

How does the greenhouse effect affect ecosystems?1 markIt promotes the growth of vegetation.It disrupts the natural balance of ecosystems.It increases biodiversity.It accelerates soil erosion.

Which of the following is a direct impact of overfishing on biodiversity?a.Improved water qualityb.Loss of marine habitatsc.Increased fish populationd.Enhanced coral reef health
