1) B
(I'm not so sure of this one) All of the other options have a steady impact on population regardless of the density of organisms except competition
2) D
Increased carbon dioxide levels would not hinder plant growth, and tsunamis aren't really linked to carbon dioxide levels. Increased carbon dioxide is unlikely to lower the air temperature so only D is left.
3) A
4) Three properties of water that allow it to sustain life are that it is adhesive, it is a good solvent, and cohesion. Adhesion is important in situations such as water travelling up xylem tubes in plants so that the water is not pulled down by gravity and can reach parts of the plant that need water. Cohesion allows the water being pulled up the xylem to stay together and for water molecules to be pulled when a neighbouring one is moved. Water being a good solvent allows inorganic minerals to be taken with water through vascular tissue, such as in the previous example.
High temperatures and greater rainfall increase the rate of chemical weathering. 2. Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions. ... Soils affect the rate in which a rock weathers.
Answer:
B
the tendency of the body to maintain inner balance despite changes in external conditions
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.
