B.Near shore zone
C.Coral reef
D.Open ocean
Answer;
D. The Open Marine ecosystem
Explanation;
An ecosystemis the lowest level of environmental complexity that includes living (biotic factors)and nonliving factors (abiotic factors).
-The Open marine ecosystem contains the fewest photosynthetic producers, this is because most producers can't live or survive in an areas with the lack of nutrients or sun light. They need nutrients for growth and also sunlight to undertake the process of photosynthesis which helps them make their own food.
The D. open ocean is the marine ecosystem that contains the fewest producers, such as phytoplankton.
Marine ecosystems are diverse and complex aquatic environments found in oceans, seas, and coastal regions. They support a wide range of life forms, from microorganisms to large marine mammals. These ecosystems play critical roles in Earth's climate regulation, nutrient cycling, and food production, making them vital for global ecological balance.
The marine ecosystem that contains the fewest producers is the open ocean. The open ocean is characterized by low levels of nutrients and sunlight, which limits the growth of producers such as phytoplankton. Instead, the primary producers in the open ocean are photosynthetic bacteria and archaea, which can thrive in these extreme conditions.

The right answer are in the picture attached.
Gametes:
A gamete is a sexual cell that allows sexual reproduction. The word gamete comes from elsewhere in ancient Greek and means "spouse".
Gametes function to merge to give birth to a new individual with unique genetic heritage.
The random loss of a chromosome of each pair allows the fertilization of two gametes with each other, whose fusion will give birth to an egg (zygote) endowed, like its parents, with 46 chromosomes.
Meiosis:
* Meiosis consists of two successive cell divisions that will give birth to gametes.
At the end of meiosis, the original cell gave birth to four haploid cells whose genomes were recombined in a unique way.
* In humans, the cells that will participate in meiosis are spermatocytes and oocytes.
* In the cells that will enter into meiosis, the replication of A.D.N. occurred during interphase, each chromosome consists of 2 chromatids connected by their centromere. (Each chromatide is composed of a double-stranded A.D.N molecule and molecules that maintain its structure).
Mitosis:
Mitosis is the process of reproducing (identical) cells.
At the end of the mitosis, the mother cell divided into daughter cells identical to each other and identical to the cell that gave birth to them.
This one can be broken down into 4 phases.
Prophase, Metaphase, Anaphase and Telophase.
Somatic cells:
The set of somatic cells, called soma, are all the cells forming the body of a multicellular organism, that is, all non-germline cells, such as gametes, or cells. germ. These last ones constitute the germen.
Somatic cells are usually the vast majority of cells that make up an individual.
Asexual reproduction (there's no asexual cells in the proposed terms):
A vegetative or asexual cycle, in the context in which this word is used here, means: which does not concern reproduction but which concerns the physiological processes that ensure life, growth, development and multiplication when it is not sexual .
A vegetative or asexual cell is said to be, as opposed to reproductive, a cell whose function is related to nutrition. See the definition of endospore and especially vegetative propagation.
Sexual reproduction (there's no sexual cells in the proposed terms):
Sexual reproduction is a reproductive process that creates a new organism by combining the genetic material of two different sex organisms through a different genital reproductive tract in both males and females. This process occurs in both eukaryotes and prokaryotes; in multicellular eukaryotic organisms, a new individual is created; in prokaryotes, there is scissiparity of the initial cell.
Somatic cells undergo mitosis for growth and form asexual cells. Gametes, produced through meiosis, are reproductive or sexual cells. Mitosis produces identical copies of cells, while meiosis produces gametes for sexual reproduction.
In understanding cell division, we need to look at four main terms: gametes, meiosis, mitosis, and somatic cells. Somatic cells are non-reproductive cells that undergo mitosis for growth and repair, leading to asexual cells, while gametes are reproductive cells (sexual cells) created through meiosis. Mitosis and meiosis are types of cell division. Mitosis divides a cell into two identical copies and is a key mechanism of asexual reproduction. On the other hand, meiosis is involved in sexual reproduction and generates gametes.

Salvatore's decision to dump his fish tank and its contents into a nearby freshwater canal could have devastating consequences for the ecosystem.
The non-native fish species from the tank could outcompete and prey on native fish, leading to disruptions in the natural balance and potentially causing local extinctions.
The uneaten fish food and waste from the tank could lead to water pollution, harmful algal blooms, and a decline in water quality, affecting aquatic plants and other animals in the canal.
This irresponsible action could harm the delicate biodiversity of the canal, disrupting the entire ecosystem and leading to long-term environmental damage.

Anything that has mass and takes up space is called matter. Matter is the term used to describe anything that possesses mass and occupies space.
Matter is a term used in the field of physics and chemistry to describe anything that has mass and occupies space. It refers to all substances and materials that we encounter in our daily lives, including solids, liquids, and gases.
The concept of matter is based on the understanding that everything in the physical world consists of tiny particles called atoms or molecules. These particles are the building blocks of matter and are constantly in motion.
The mass of an object refers to the amount of matter it contains, which determines its inertia and gravitational attraction. The space occupied by an object refers to its volume, which can be measured or observed in terms of its dimensions or displacement of other substances.
Matter exists in various forms and states, ranging from the solid state (e.g., rock, metal) where particles are closely packed together, to the liquid state (e.g., water, oil) where particles are more loosely arranged and can flow, to the gaseous state (e.g., air, oxygen) where particles are widely spaced and move freely.
Understanding matter and its properties is fundamental to the study of chemistry, physics, and other scientific disciplines. By examining the behavior and interactions of different types of matter, scientists can gain insights into the structure of substances, the nature of chemical reactions, and the principles governing the physical world.
In summary, matter is the term used to describe anything that possesses mass and occupies space. It encompasses all substances and materials in different states and is the subject of study in various scientific fields.
