Describe how an algal bloom might alter the local carbon cycle in that ecosystem.

Biology
1 answer:
AlladinOne [14]3 years ago
4 0

Answer:

Explanation:

During an algal bloom the species produce a toxic chemical substance which is harmful to animals that feed on the algae that causes a tint in the water because of the photosynthetic pigments is known as a red tide a red tide may or may not be harmful . Nonetheless algal bloom can produce both beneficial and harmful cycles.

It is beneficial because it can provide organic compounds needed by higher organisms, for this reason productivity increases because there's more algae in the water which means that more carbon dioxide is used from the atmosphere and that more oxygen is being released into the atmosphere which is needed and necessary for many living things

The illustration shows one of the ways resources are removed from the deep sea. Describe what type of resources these are, inclu
just olya [345]

Answer:

Marine mining is a process that can be done by dredging the seabed and is used for the extraction of mineral resources from the seabed, which are non-renewable, with a negative impact on marine ecosystems.

Explanation:

The illustration shows a process of marine mining by dredging, where the resource extracted is of a mineral nature, like copper, zinc, silver and gold. Gravel used for construction can also be extracted from the sea. Mineral resources extracted from the sea are not renewable.

The process of marine mining can be harmful to the ecosystems there, so it must be a process that requires control and management from the ecological point of view.

Two possible consequences of not regulating marine mining are:

  1. <u><em>Destruction of the habitat of life forms present on the sea floor</em></u><em>, which endangers many species and even forces migration to more stable areas, with consequences on the food chains. </em>
  2. <em><u>Extinction of marine species that inhabit the seabed</u></em><em>. The flora and fauna of the sea floor usually have slow reproductive cycles and, in the case of fish, spawning takes place on the bottom of the sea. Mining endangers the reproductive cycles of the species, leading to induced extinction.</em>

Responsible and controlled mining activity can be useful for humans, while avoiding negative consequences on the ecosystems that exist at the seabed.

Delicious77 [7]

Student 1’s methods would be more accurate, because the student would control more factors. Only one variable at a time (either temperature or acidity) would be tested on each group of worms. On the other hand, Student 2 is testing both factors on all the worms, which could make the results unclear.

Atmospheric carbon dioxide dissolves into ocen surface waters
Elan Coil [88]

Answer:

Carbon dioxide, which is naturally in the atmosphere, dissolves into seawater. Water and carbon dioxide combine to form carbonic acid (H2CO3), a weak acid that breaks (or “dissociates”) into hydrogen ions (H+) and bicarbonate ions (HCO3-).

Define the following terms with examples:
Mashcka [7]

1) Chordata=A chordate is an animal of the phylum Chordata. All chordates possess 5 synapomorphies, or primary characteristics, at some point during their larval or adulthood stages that distinguish them from all other taxa

2) Vertebrates=vertebrate, also called Craniata, any animal of the subphylum Vertebrata, the predominant subphylum of the phylum Chordata. The vertebrates are also characterized by a muscular system consisting primarily of bilaterally paired masses and a central nervous system partly enclosed within the backbone.

3)Invertebrates=Invertebrates are animals that neither possess nor develop a vertebral column, derived from the notochord. This includes all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelid, and cnidarians.

4) Poikilothermic animals=A poikilotherm is an animal whose internal temperature varies considerably. Poikilotherms have to survive and adapt to environmental stress.

5) Homeothermic animals=The term homeothermic refers to the warm-blooded animals which have constant and relatively higher temperature. They are animals which can maintain their internal body temperature. Complete answer: Homeothermic animals are warm-blooded and maintain a constant body temperature, for example birds and mammals.

6) Oviparous= producing young by means of eggs which are hatched after they have been laid by the parent, as in birds.

7)Vivaparous=bringing forth live young which have developed inside the body of the parent

Sorry if it's incorrect

Have a nice day
