Ecosystems

Krill are the main food source of many sea animals, such as whales. When the krill die, so do their predators, and the predators that eat those predators, etc etc etc. So pretty much, a whole lot of the sea life food chain collapses.

Yes, a parasite occupies an ecological niche. Parasites depend on a host organism for survival and reproduction, making use of a specific set of resources within an ecosystem. They play a role in balancing ecosystems by regulating host populations and contributing to biodiversity.

Once an organism consumes a living thing, it gets energy from it. In a food pyramid, only 10% of the energy is passed on to the consumer. For example if an organism had 1000 calories of energy in it, and it was eaten, the predator would have gotten 10% of 1000 or 100 calories. If an animal eats that animal, it gets 10% of 100 in energy; 10 calories. And so on...

NOTE- This is why food pyramids have so few tropic levels

don't quite understand the question - it all depends on the type of animal - a herd of cattle, or sheep. A pride of lions. A murder of crows. A flock of birds etc... it depends on the what species it is!

Yes, carrying capacity can change with time due to factors such as environmental changes, resource availability, and population dynamics. For example, a decrease in resources or an increase in competition can lower carrying capacity, while habitat restoration or improved technology can raise carrying capacity.

Factors that would not decrease the carrying capacity of a pond environment include increasing sunlight exposure, providing additional nutrients for plant growth, and implementing sustainable aquatic life management practices.

Top level consumers in the ocean include apex predators such as sharks, killer whales, and swordfish. These predators are at the top of the food chain and play a crucial role in maintaining the balance of the marine ecosystem.

Toco toucans share their environment with a variety of animals, including other bird species like parrots and hummingbirds, as well as mammals like monkeys and sloths. They also interact with reptiles such as snakes and lizards in their habitat.

Water chestnuts (Trapa natans) are considered invasive species in certain regions, such as North America. They can outcompete native vegetation, clog waterways, and disrupt ecosystems. Efforts are often made to control their spread and mitigate their impact on local ecosystems.

An example of two species dividing a habitat is when different species of warblers occupy different levels in a forest canopy to avoid direct competition for resources. Another example is when different species of hummingbirds have evolved different flower preferences based on tube length, allowing them to coexist in the same habitat by feeding on different types of flowers.

If you think of the planet it is easy to picture the two main ecosystems for the planet. Land and water. These are called Terrestrial and Aquatic. These are then broken down into sub-categories. Hello from Earth Science Coral Springs High School

The nonliving environment in Carnarvon Gorge includes abiotic factors such as temperature, rainfall, sunlight, soil composition, and geological formations. These elements play a crucial role in shaping the physical landscape of the gorge and influencing the distribution of living organisms within the ecosystem.

A Burmese python can disrupt the ecosystem by preying on native species, causing a decline in their populations. They can also outcompete native predators for food resources, potentially leading to imbalances in the ecosystem. Their presence can alter the natural dynamics and biodiversity of an ecosystem where they are introduced.

In the environment, everything is reusable and replenishable but at a certain rate. The certain rate is the much environment can balance itself. Overly consume or damage would break the balance beyond the point of restorable.

For the example of imbalance. Fish is replenishable goods of seas. However, near shore fishery using fishing net cause damage to corals where fish would breed and thus imbalance in the environment. This imbalance would results to extinction and no more fish for fishing.

Decomposition is a gradual process where microorganisms break down animal tissue, releasing nutrients back into the environment. This important ecological process plays a role in nutrient cycling and soil formation.

A scrub jay is a consumer because it gets its energy by eating other organisms, such as insects, seeds, and small fruits. It is not a decomposer (which breaks down dead organic matter) or a producer (which makes its own food through photosynthesis).

Excessive nutrients in the water can lead to algal overgrowth, which can smother coral and disrupt their ability to photosynthesize. This can weaken the coral and make them more susceptible to disease. Additionally, increased nutrient levels can also lead to ocean acidification, further stressing the coral.

Ivan Pavlov, a Russian physiologist, was the first biologist to demonstrate classical conditioning in dogs. He famously showed that dogs could learn to associate a neutral stimulus, like the sound of a bell, with a reflex response, like salivating for food, through repeated pairings of the two stimuli.

Biotic factors are living or once-living organisms within an ecosystem. They can include animals, plants, fungi, bacteria, and more. In terms of appearance, biotic factors can vary widely depending on the specific organism.

Many things eat abalone, such as seals, who pry them open to eat the fleshy insides. Some species of birds also eat them.

Yes, it is estimated that more than 50 percent of the Earth's ecosystems are being used unsustainably, leading to degradation and loss of biodiversity. This includes practices such as deforestation, overfishing, and pollution that exceed the capacity of ecosystems to regenerate and provide essential services. Sustainable management and conservation efforts are crucial to preserve these ecosystems for future generations.

Abiotic factors for bull sharks include water temperature, salinity, and oxygen levels. Biotic factors include their prey, such as fish and other marine animals, as well as competitors within their ecosystem.

Greater temperature fluctuations typically occur during seasonal transitions, such as from winter to spring or from summer to fall. This is because the shifts in weather patterns and atmospheric conditions during these times can lead to more pronounced changes in temperatures. Additionally, regions with continental climates or areas affected by specific weather patterns like cold fronts or heat waves may also experience greater temperature fluctuations.

A density dependent factor is a limiting factor that depends on population size. A Density-independent limiting factor affects all populations in similar ways, regardless of the population size. Its in my biology book.

Lions are predators in the food chain, consuming herbivores which in turn consume plants. Through this interaction, lions indirectly contribute to the cycling of nutrients, including carbon, as the remains of their prey decompose and release carbon back into the ecosystem.
