I think the correct answer from the choices listed above is option C. The continent that was not covered by ice during the Pleistocene ice age. This is because the southern location of this nation made it much harder for ice to form, even during this time. Hope this answers the question.

PLEASE ANSWER FIRST GETS BRAINLIEST
nikklg [1K]

Answer:

1. The numbers of amphibians are declining only in the high-risk areas of the world - False. Amphibians are declining all over the world, in which many are going extinct due to climate change and changes inside their ecosystem. Failure to adapt to the 'new' setting leads to their demise.

2. Many amphibian species are threatened, but none have recently become extinct. - False. Within the previous century, there has been documentation of either extinct or a high-chance of extinction due to failure to see any sign of existence.

3. The health of falcon populations in the 1960s indicated that pesticide use was harming the environment - True. Pesticide is generally made of poison that either kill or dissuade the pests to eat all of the crop. Any animals that falcons eat (primary consumers) that eat the pests infected by the pesticide, would in turn infect the falcon in a larger percentile, leading to death. This is a slow destruction of the Food web from the bottom up, and would lead to a collapse when one or more level of the food web is wiped out.

4. Amphibians have been part of life on Earth for only about 4 million years - False. This highly depends on the person's own beliefs, however, as the Big Bang theory has already been proved false, and school's only clutch onto it in hope.

5. Birds and fish are frequently used as indicator species - True. The usage of animals that are either primary or secondary consumers (but not producers are tertiary consumers) are good indicators of the other populations within the area. A shortage of the population can mean that the Apex has eaten way too much, and that the base animals may have overpopulated.

6. I do not have the selection, so I cannot answer it.

7. Amphibians are good indicators species, for they are secondary consumers, meaning that they consume other animals, and are also consumed by other animals.

8. Scientists can learn how certain amphibians breed with each other (mating), as well as what key factors they try to find in their environments when choosing breeding grounds. They also can then take notice on how the amphibians grow, and what factors may keep them from growing, or vice versa.

9. Additive causes means that a "cause" is added into the ecosystem, for example, the adding of pollution or other man-made waste, as well as the introduction of competing species against the native species, or an introduction of a new predator species that preys on the native one. This means that since there is a larger population of consumers, the base population of amphibians would slowly decrease.

10. Inductive reasoning allows for people (specifically scientists in this case) to try to find out about changes in a certain ecosystem by trying to prove the  hypothesis created and whether they are right or not. For example, the Inductive reasoning can be that "the Secondary Consumer's population is dropping". This reasoning (conclusion) would then have to be proved.

Luba_88 [7]

Answer: a food-growing practice that uses no synthetic fertilizers, insecticides, fungicides, or herbicides

Explanation:

Organic agriculture is a process of crops of economic importance. It is an integrated farming system that ensures the sustainability, enhances the fertility of the soil, and that is biological diversity.

It prohibits the use of synthetic pesticide or insecticides, fungicides, synthetic fertilizers, growth hormones, antibiotics, and genetically modified organisms for the growth of crops. It utilizes the fertilizers of organic origin, like manure, compost, bone meal and also supports the crop rotation. It supports the biological pest control and fostering of insect predators.
