How is energy transferred through a community of organisms glencoe?
In an ecosystem, energy is transferred via the food chain, starting from the sun to producers, then to consumers. With each transfer, some energy is lost as heat, in accordance with the Second Law of Thermodynamics.
Explanation:Energy is transferred through a community of organisms, often called an ecosystem, via the food chain or food web. It begins with the sun, the primary source of energy. Plants or producers capture sunlight through photosynthesis and convert it into chemical energy stored in glucose. Herbivores or primary consumers eat these plants, thereby receiving the stored energy. Carnivores (secondary and tertiary consumers) eat the herbivores and other carnivores, each time transferring energy. However, with each transfer, some energy is lost to the environment as heat following the Second Law of Thermodynamics which states that during energy transformations, the quality of energy decreases while its entropy increases.

Beavers kill trees by cutting them down. They then use these trees to dam streams. They also help in creating ponds. This increases the biodiversity of the place because it modifies the distribution and population of many plants and animals. Which type of species are beavers?
Answer:
Engineers
Explanation:
Beavers are called ecosystem engineers by ecologists because the change their ecosystem by cutting trees present in their ecosystem and make dams over the river by these trees, dig channels and build lodges.
These dams alter the river flow and results in the formation of a lake which have still water. Over time many still water-loving animals and plants occupy the ponds and make a new ecosystem in that area. So by making dams beavers helps in increasing the biodiversity of the place.
So due to the capability of beavers to bring change in its ecosystem, they are called ecosystem engineers.
In the domain system of classification, prokaryotes are divided into two domains: Bacteria and Archaea. The two domains differ in all BUT one feature. That is, both
That is, both have prokaryotic cells
The two prokaryotic domains differ greatly but all organisms in these domains have prokaryotic cells. Members of the domain Archaea live in extreme environments, including anaerobic conditions. Also, the Archaea have cell walls that are different from the Bacteria as their walls do not contain peptidoglycan. Some scientists believe the Archaea to be more closely related to the eukaryote.
Carolus linnaeus is considered to be the founder of __________, and he __________.
Carolus Linnaeus is considered to be the founder of modern taxonomy, and he made significant contributions to the classification and naming of organisms.
Taxonomy is the science of categorizing and naming organisms based on their shared characteristics. Linnaeus developed a hierarchical system of classification that is still used today. His system includes grouping organisms into categories such as kingdom, phylum, class, order, family, genus, and species. Linnaeus also introduced the binomial nomenclature, which is a naming system that uses two Latin words to identify each species. The first word represents the genus, and the second word represents the species. For example, humans are classified as Homo sapiens, where Homo is the genus and sapiens is the species.By organizing and naming organisms in a systematic way, Linnaeus provided a foundation for the study and understanding of biodiversity. His contributions continue to be influential in the field of biology, allowing scientists to communicate and classify organisms accurately and efficiently.

Information coming into the central nervous system is transmitted along ________ neurons
The neurons responsible for transmitting information to the central nervous system are known as sensory neurons. These neurons respond to specific stimuli, generate electric signals, and transmit this information to the central nervous system.
Explanation:Information coming into the central nervous system is transmitted along sensory neurons. Sensory neurons are specialized types of neurons designed to respond to specific types of stimuli such as light, sound, heat, or pressure. Once the stimuli is received, sensory neurons generate electric signals that are transmitted to the central nervous system where the information is processed, interpreted, and a response is generated. For instance, if you touch a hot surface, sensory neurons in your skin perceive the high temperature and send this information to your central nervous system, leading to your reflexive action of pulling your hand away.

How do worms reproduce?
a. only sexually.
b. only asexually.
c. both sexually and asexually.
d. none of the above?
Worms, depending on the species, can reproduce option c. both sexually and asexually. Annelids, like earthworms, can reproduce in both ways, whereas flatworms generally reproduce sexually.
They fertilize their own eggs after exchanging sperm with another worm during sexual reproduction. They can also reproduce asexually by budding or fission, for example.
Flatworms, on the other hand, typically reproduce sexually. After fertilization, a single flatworm produces both eggs and sperm, and the eggs turn into larvae outside the adult flatworm's body.
Nematodes, like C. elegans, also use a variety of reproductive methods. Depending on the species, these may include dioecious reproduction, monoecious reproduction, self-fertilizing hermaphrodites, or even asexual reproduction through parthenogenesis.

Which shows the pathway of the egg through the reproductive system?
A. ovary → fallopian tube → vagina → uterus
B. vagina → uterus → fallopian tube → ovary
C. fallopian tube → ovary → uterus → vagina
D. ovary → fallopian tube → uterus → vagina
Answer:
D. ovary → fallopian tube → uterus → vagina
Explanation:
The egg/ovum develops in ovary. Ovary is a specialized organ in female reproductive system which is meant for the production and development of ovum. The ovum lies with in the follicle present inside ovary. The follicles mature from primordial follicle to primary follicle which then matures into secondary follicle, secondary follicle in turn matures into tertiary follicle and eventually it forms graafian follicle within the ovary. During the development of ovum, these follicles undergo several physiological changes. On the day of ovulation, graafian follicle ovulates its egg into the fallopian tube which is a part of female reproductive system. The fallopian tube has finger like projections named fimbriae which act as the receptor of the ovum. After that comes uterus which is also known as womb where embryo gets implanted. The uterus ends in vagina which is a part of birth canal.
