Aquatic environment:
The general meaning of the word migration is to move from one place to another.
Fish species migrate with the change of seasons annually, monthly or daily.
The factors are probably abiotic in nature, for example: temperature change, photoperiod, salinity, lunar cycle, precipitation, currents and foraging areas.
A migrant fish is visually obvious due to the mass of numbers. Many fish migrations are evident due to their precise timing, making such fish movements noticeable. They live in marine, brackish and fresh waters, distributed throughout the world.
The seas and rivers offer a variety of species that are advantageous for human consumption and in the commercial industry such as shrimp, lobsters, crabs and others. The government has established a period of prohibition in order to protect the existence of species of marine resources that allow their reproduction and conservation.
In relation to fishing, the use of poisonous substances derived from the leaves, crusts or roots of certain trees is prohibited, since they cause the death of large and small fish. Hunting or capturing certain species has a period of prohibition: 1. Time of ovulation and growth of the shrimp.
2. Hatching period for iguana and turtle eggs. Terrestrial environment: Plants and animals breathe, but only plants can photosynthesize. The main reservoir of carbon dioxide is found in the oceans and rocks.
Oxygen: All oxygen in the atmosphere is biogenic; This means that it was released from the water by photosynthesis from the autotroph's organism. All living things can be divided into autotrophs and heterotrophs according to their energy pathways.
Carbon: From a biological perspective, respiration takes carbohydrates and oxygen to produce carbon dioxide, water, and energy, and photosynthesis takes carbon dioxide, water to produce carbohydrates, and oxygen.
Wind: It is a source of clean energy but the specific problems related to health and the environment originate from emissions from industries, factories for mineral processing and other operations.
Soil: Soil reaction is really significant for crop production and management. The different grades that are produced by chemical conditions can be favorable for some crops, unfavorable for others, and in others they can affect very little plant growth in a certain structure.
I- Answer the questions about the previous text.
1. Why does the government have a ban period to capture certain
species? The closures, which are the periods in which the capture of species is prohibited to avoid the depredation of natural resources and allow their reproduction and subsistence. … The closed time is established by the Federal Government and there are different periods for each species, which you can consult on the Conapesca portal.
2. When do fish species migrate? With the change of seasons annually, monthly or daily.
3. Name some species of fish that are used for food and industry. Species such as grunt, gurrabato, boquilla, horse mackerel, cabrilla, bonito and hake are some of the fish and shellfish
II- Match the words in column A with the information in column B.
1. Oxygen is Aa. a clean energy source.
2. Carbon is D b. for crop production.
3. The wind is A c. biogenic.
4. The soil is B d. produced by carbohydrates and oxygen.
III- Fill in the blanks according to the text.
1. A __________ is visually obvious due to the mass of numbers
2. Hunting or capturing certain species has a period of time
3. Fishing with poisonous substances is prohibited, since they cause the
large and small fish kills.
