Answer: Diversity, referring to the state of having many different organisms cohabitate within an area is a desirable outcome for many ecosystems. The presence of a wide spectrum of different organisms allows for more life to be able to thrive in an ecosystem. For example, an ecosystem with a wide array of shrubs, grasslands and forested areas is able to accommodate more life forms than an ecosystem of just forest. This increased capacity to support life directly improves the capacity of the biosphere to support life as well, diversity leading to growth.
The correct options are:
- Matter is made of small particles.
- Matter's particles are in constant random motion or vibration
- There is empty space between matter's particles.
Anything which has mass and occupies shape is a matter. Matter is composed of particles. The particles of matter are very small in size and they attract each other. There is space between the particles. The particles are in continuous random motion, thus they have kinetic energy. on absorbing energy their movement increases.
Answer: The answer is A. Comparative
Explanation: The photo shows two different types of soil with the same type of worm. Therefore this it a comparative experiment. Trust me I got this question correct.
Answer:
I'm thinking maybe B, illustrates the principle of natural selection.
Explanation:
This example shows that, once a particular event happens in a species' ecosystem that negatively affects their lifestyle, natural selection occurs and kills off those with a disadvantageous adaptation (in this case the narrow-beaked finches, since they could no longer eat insects but did not have the beak size to crack seeds), allowing those with the advantageous adaptation (in this case, the thicker-beaked birds) to prosper.
