Answer:
The first statement is true
1) Ecology is the scientific study of the distribution and abundance of organisms, the interaction among organisms, and the interactions between organisms and their abiotic environment. Ecologists try to understand the inner workings of natural ecosystems and the species they contain.
2) Ecosystems have no particular size. An ecosystem can be as large as a desert or a lake or as small as a tree or a puddle. If you have a terrarium, that is an artificial ecosystem. The water, water temperature, plants, animals, air, light and soil all work together.
3) The biotic factors of an ecosystem include all the populations in a habitat, such as all the species of plants, animals, and fungi, as well as all the micro-organisms. Also recall that the nonliving factors are called abiotic factors. Abiotic factors include temperature, water, soil, and air.
4) For aquatic ecosystems, these factors include light levels, water flow rate, temperature, dissolved oxygen, acidity (pH), salinity and depth.
Hope this helped. ;)
The words for the descriptions are food chain, trophic level, energy pyramid, high diversity, low diversity, etc. respectively.
<h3>Ecology</h3>
- The feeding relationship that exists among organisms is termed the food chain.
- Each step in the transfer of energy and matter in a community is termed the trophic level.
- A community or group of living organisms that live in and interact with each other in a specific environment is termed an ecosystem.
- A diagram that compares the energy used by producers, primary consumers, and other trophic levels is known as the energy pyramid.
- An ecosystem with a high number of species is said to be of high diversity.
- An ecosystem with a few prominent species and a low number of other species is said to be of low diversity.
- Organisms that feed on and break down organic matter are said to be decomposers.
- Organisms that can make their own food in the ecosystem are termed, producers.
- Animals that feed on flesh are called carnivores.
- A system of interlocking and interdependent food chains is called a food web.

B) They should test their hypothesis before coming to that conclusion.
Answer:
10 meters/second.
Explanation:
Unladen swallow consists of two species are <em>Hirundo domicella </em>and the <em>Hirundo spilodera</em>.
The average speed of unladen swallow comes out to be 10 meters/second. The maximum speed can go upto 13-14 meters/second. The speed of unladen swallow can be calculated by the formula given by Graham K. Taylor. According to graham the speed of unladen swallow is 3 times of the product of frequency and amplitude. ( v= 3fA, v is velocity, f is frequency and A is amplitude).
