Ecosystems

An earthworm's excretory system contains pairs of integumentary, septal, and pharyngeal nephridia. Each nephridia is located in a different segment of the body.

Yes, parasites are biotic factors because they are living organisms that interact with other organisms in an ecosystem by exploiting them for nutrients and resources. They play a role in the balance of populations and can impact the health of the host organism.

Carrying capacity limiting factors, such as availability of resources like food and space, help regulate population growth by preventing it from exceeding the environment's capacity to support it. Predation acts as a natural control mechanism by keeping population numbers in check through the consumption of individuals, which helps prevent overpopulation and maintain balance in ecosystems. Together, these factors work to ensure that the population size remains within sustainable limits in a given habitat.

E. coli is heterotrophic, meaning it relies on organic compounds as a source of carbon for growth and energy production. It cannot produce its own food through photosynthesis like autotrophic organisms.

The northern copperhead is typically found in forests, rocky areas, and along the edges of streams or wetlands. They prefer habitats with plenty of cover such as fallen logs, leaf litter, and rocks where they can hide and hunt for prey. They are primarily found in the eastern United States.

Around 1.7 million species are currently described by science, however it is believed that there are at least 5 - 7 million more species that are as yet undocumented.

A road runner's ecosystem typically includes desert and arid regions. They are found in North and Central America, where they occupy various habitats such as grasslands, chaparral, and scrubland. They are opportunistic feeders, preying on insects, reptiles, small mammals, and even other birds.

All living beings respond to stimuli.All living beings respire.All living beingsreproduce.All livings can grow. So, I think these all characters are shown by trees.So they are also living beings.

tallest malunggay tree is reaching for about 21 feet.

The ghost of competition past refers to lessons or failures from past competitions that continue to haunt or influence present decisions and behaviors in competitive situations. It suggests that past experiences and outcomes in competitive environments shape future strategies and approaches.

Lactobacillus acidophilus is a heterotroph, meaning it obtains carbon from organic compounds. It is unable to produce its own organic molecules from inorganic sources.

Okay. Firstable, there are 3 kinds of symbiosis : parasitism, mutualism and commensalism. If u want to understand it ezly. Paratism=one of them good others are super-bad. e.g.)tapeworms, lampreys whatever... mutualism=both of them happy e.g.)alga+fungus&linchens, birds commensalism=one of them is happy others not happy not sad (so so) the answer 4 ur Q is The association of an alga and a fungus in linchens is another example of mutualism. the nonphotosynthetic fungus provides moisture and support for the alga, which in turn synthesizes food for the fungus and itself. did u like it? i hope u did.

Advantages of being diurnal include increased visibility, ability to take advantage of daylight for activities, and alignment with societal schedules. Disadvantages include potential exposure to predators during the day, competition for resources with other diurnal species, and limited opportunities for foraging during nighttime hours.

The population would decrease significantly, and perhaps die out. This is because the birth rate would be small and the death rate would be large. As the "old" individuals die, there will not be enough "babies" to replace them.

1. Volcanic islands: When a new volcanic island emerges from the ocean, primary succession occurs as lichens and mosses colonize the barren rock, followed by grasses and shrubs, eventually leading to the establishment of a more complex ecosystem.

2. Glacier retreat: As glaciers recede, they leave behind barren land devoid of vegetation. Primary succession then takes place as pioneer species such as lichens and mosses establish themselves, paving the way for the development of a new ecosystem over time.

In parasitic relationships, one organism benefits at the expense of another. The parasite benefits by deriving nutrients or resources from the host, often leading to harm or negative effects on the host. Parasites have evolved various strategies to exploit hosts for survival, such as feeding on host tissues or fluids, while the host may exhibit defensive mechanisms to limit the parasite's impact.

The largest reserves of phosphorus are found in Morocco, specifically in the Western Sahara region. Phosphorus reserves are mainly mined for use in fertilizers to support agricultural production.

In secondary succession, there may be remnants of soil and organic matter left over from the previous ecosystem, which is not typically present in primary succession. This can provide a foundation for plant growth and help jumpstart the regeneration of the ecosystem.

Examples of biotic robot ideas include robots inspired by animals or plants to perform tasks such as surveillance (like a robot inspired by a butterfly for aerial reconnaissance), exploration (like a robot inspired by a snake for maneuvering through tight spaces), or search and rescue (like a robot inspired by a cheetah for fast mobility over rough terrain). These biotic robots mimic the natural movements and abilities of living organisms to enhance their performance in specific tasks.

The main limiting factors of the African Savannah are water availability, nutrient-poor soil, and fire. The savannah experiences long dry seasons, leading to water scarcity for plants and animals. The soil is often nutrient-poor, affecting plant growth. Additionally, frequent fires play a role in shaping the ecosystem and influencing plant diversity.

Fungi and worms play key roles in the carbon cycle by breaking down organic matter and returning nutrients back to the soil. Fungi decompose dead plant material, releasing carbon into the soil, while worms help aerate the soil and facilitate the decomposition process. This helps regulate carbon levels in the ecosystem and promotes nutrient cycling for plant growth.

Various types of bacteria, such as Pseudomonas and Vibrio species, are involved in the decomposition of dolphins once they die. These bacteria break down the tissues and organic matter, playing a crucial role in the natural recycling of nutrients back into the ecosystem.

Komodo Dragons are top predators in their ecosystem, helping to regulate the populations of prey species such as deer and pigs. They also scavenge on carcasses, helping to recycle nutrients back into the ecosystem. Their presence influences the behavior and distribution of other species in their environment.
