1.
Which adaptation would BENEFICIAL (helpful) for an organism living in an underwater biome?
Correct Answer
C. The ability to absorb nutrients directly from the water
Explanation
An organism living in an underwater biome would benefit from the ability to absorb nutrients directly from the water. This adaptation would allow the organism to obtain essential nutrients for survival and growth without the need for external food sources. By directly absorbing nutrients from the water, the organism can efficiently utilize the resources available in its environment, increasing its chances of survival and reproductive success.
2.
What TWO facts would be true if EUTROpHICATION happened in a pond?
Correct Answer(s)
B. Too much algae & plants grow
C. Oxygen is DEPLETED for the fish
Explanation
If eutrophication occurs in a pond, it means that there is an excessive amount of nutrients available in the water. This abundance of nutrients leads to an overgrowth of algae and plants, resulting in too much algae and plants growing in the pond. Additionally, this excessive growth leads to a depletion of oxygen in the water, which negatively affects the fish population. Therefore, the two true facts if eutrophication happened in a pond would be too much algae and plants growing and oxygen depletion for the fish.
3.
Which TWO organisms would HIBERNATE in the winter?
Correct Answer(s)
C. Bears
D. Snakes
Explanation
Only animals hibernate. Plants DO NOT hibernate. Plants do dormancy during the winter.
4.
Which picture shows NEGATIVE pHOTOTROPISM?
Correct Answer
A. A
Explanation
Negative phototropism is when plants grow away from direct sunlight toward the shade. They don't want to dry out.
5.
What would be the direction of SUCCESSION (change) of an ecosystem?
Correct Answer
B. PIONEER (new) species develop into a MATURE species.
Explanation
The correct answer is that pioneer species develop into a mature species. This means that in the succession of an ecosystem, the initial pioneer species, which are typically hardy and adaptable, gradually give way to more complex and mature species over time. These pioneer species create the conditions necessary for the establishment of a more diverse and stable ecosystem. As the ecosystem develops, the pioneer species are replaced by more specialized and mature species, leading to a succession of different species in the ecosystem.
6.
Which biome would have animals that would BURROW (dig) into the ground during the day so they can hunt at night?
Correct Answer
A. Desert
Explanation
These animals are staying out of the hot sunlight during the day. They hunt at night to avoid the heat and sunlight of a desert.
7.
Which biome has huge leaves, waxy tops to help water runoff to the ground?
Correct Answer
D. Rainforest
Explanation
Rainforests have huge leaves and waxy tops to facilitate water runoff to the ground. The large leaves allow for maximum surface area for capturing sunlight, while the waxy tops help to repel water and prevent it from saturating the leaves. This adaptation is necessary in rainforests, which receive high amounts of rainfall throughout the year. The ability to efficiently shed water helps prevent the leaves from becoming waterlogged and allows for better absorption of sunlight for photosynthesis.
8.
These SUCCULENTS (water holders) are found in which biome?
Correct Answer
B. Desert
Explanation
Succulents are plants that have adapted to arid environments by storing water in their leaves, stems, or roots. They are commonly found in desert biomes, where water is scarce and the climate is dry. In deserts, succulents thrive due to their ability to retain water and survive in extreme conditions.
9.
In which biome would an animal who absorbs nutrients directly from water THRIVE?
Correct Answer
B. Freshwater aquatic
Explanation
An animal that absorbs nutrients directly from water would thrive in the freshwater aquatic biome. This is because the freshwater aquatic biome consists of bodies of water such as lakes, rivers, and ponds, which provide the necessary environment for the animal to absorb nutrients directly from the water. In contrast, the coniferous forest biome is a terrestrial biome dominated by trees, and the desert biome is characterized by arid conditions with limited water availability, making them unsuitable for an animal that relies on absorbing nutrients from water.
