1. An example of secondary consumer is snake. Secondary consumers are the ones who eat the primary consumers, which makes them carnivore.
2. Photosynthesis is a process used by plants and (some other organisms) that converts water (H2O) and carbon dioxide (CO2) with the presence of sun energy (collected in the chloroplasts) into chemical energy that is later stored in sugars (carbohydrates). Organisms that do the photosynthesis are called autotrophs (produce food by themselves).
3. The energy pyramid represents energy flow in a community, where the different levels represent different groups of organisms.
The food chain is a circulation of energy that comes from the sun and passes from the producer organisms to the primary consumer, secondary and tertiary consumer organisms.
4. For example, plant is producer that is eaten by primary consumer-herbivore (e.g. bugs). Than secondary consumer-carnivore (e.g. snake) eat that herbivore and than is being eaten by tertiary consumer (apex predator that have no natural predator).
5. One trophic level gets only 10% of the energy of the previous level. So, if the plant have 10.000 units of energy and is eaten by rabbit, rabbit gets 1000 units of energy, and when the fox eats an rabbit, it gets 100 units of energy.
6. Trophic level is the position of an organism in the food chain.
Answer:
evaporation, condensation, and precipitation. Evaporation is the process of a liquid's surface changing to a gas. In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor. condensation water which collects as droplets on a cold surface when humid air is in contact with it. Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain. properties of ocean water.Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity. The two basic types of currents – surface and deep-water currents – help define the character and flow of ocean waters across the planet.On the landscape, freshwater is stored in rivers, lakes, reservoirs, and creeks and streams. Most of the water people use everyday comes from these sources of water on the land surface. Lakes are valuable natural resources, both for human and non-human life.
<h3>Answer;</h3>
Climatic limitations of the area
<h3><u>Explanation;</u></h3>
- Climatic climax is a stage in which the plant species live in perfect balance with the current environmental conditions. Although climate is the major influence on vegetation at a global scale, on a local scale other factors such as drainage, geology and relief affect plant growth.
- In the process of ecological succession, one community replaces another until a climax community is established. The type of climatic vegetation that grows in a certain geographical area is most directly influenced by a climatic limitations of an area.
- <em><u>A climax community is able to exist in a certain geographic region for a long period of time because it remains in equilibrium with the environment.</u></em>
- <em><u>Ecosystems tend to change with time until a stable system is formed. All stable ecosystems are characterized by the presence of a specific climax vegetation influenced by the climate of the area</u></em>.
Answer:
As a cell prepares to divide, it must make a copy of each of its chromosomes. The two copies of a chromosome are called sister chromatids.
