Ecosystems

Our community is changing with the introduction of new technologies, shifting demographics, and evolving societal values. There is a growing emphasis on sustainability, diversity, and inclusivity, which is driving positive changes in our community's structure, culture, and opportunities. Collaboration and innovation are key as we navigate these changes to create a more vibrant and resilient community.

Extraterrestrial life.

One way oxygen moves between the biosphere and the atmosphere is through the process of photosynthesis. During this process, plants and other photosynthetic organisms take in carbon dioxide from the atmosphere and release oxygen as a byproduct, thus increasing the oxygen levels in the atmosphere.

As a carnivore and scavenger, the dingo is perfectly adapted to living of the injured native fauna. After white man settled in Australia, the dinoges diet included new born lambs and calves, injured rabbit and cats.

Estuarine Wetlands are wetlands occurring in the Estuarine System, one of five systems in the classification of wetlands and deepwater habitat . Estuarine wetlands are tidal wetlands that are usually semi-enclosed by land but have open, partly obstructed or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The most common example is where a river flows into the ocean

Living things are organisms that show characteristics of life, such as growth, reproduction, response to stimuli, and the ability to obtain and use energy. They are made of cells, can adapt to their environment, and carry out metabolic processes for survival. Living things have the ability to evolve and maintain homeostasis to ensure their continued existence.

You can remember the word "niche" by associating it with a specific role or position that a organism occupies in its ecosystem. Additionally, you can think of "niche" as the unique space or environment in which something thrives or is most suited for.

I have 2 pet axolotls and have watched them eat plenty of times.

They stay perfectly still at first when their prey swims in front of them, they then let themselves float up a little and then snap.

If its dead they judge the corpse on scent rather than movement. Axolotl tadpoles do not have a sense of smell which is why they rely on movement. Their sense of smell comes around when they're about 2 months old.

Food chains

A food chain shows the different organisms that live in a habitat, and what eats what.

Producers and consumers

A food chain always starts with a producer, which is an organism that makes its own food. This is usually a green plant, because plants make their own food. (A process called photosynthesis)

A food chain ends with a consumer, which is an animal that eats a plant or other animal.

A consumer that eats plants is called a herbivore

A consumer that eats other animals is called a carnivore

An omnivore is an animal that eats both plants and animals

Predators and prey

A predator is an animal that eats other animals

The prey is the animal that gets eaten by the predator

The levels of organization in multicellular organisms typically include cells, tissues, organs, and organ systems. Cells group together to form tissues, tissues work together to create organs, and organs collaborate to form organ systems that function together to support the organism's overall health and survival.

Pioneer species are the first plants to colonize a new or disturbed environment. Their role in succession is to establish stable conditions for other plant species to thrive by improving soil quality and providing shelter for more complex organisms. Over time, pioneer species are gradually replaced by more competitive and diverse plant species, leading to a more mature ecosystem.

Carbon dioxide can be absorbed by plants during photosynthesis and stored as carbon in their biomass, contributing to the formation of fossil fuels over time. Alternatively, carbon dioxide can be released through the combustion of fossil fuels, deforestation, or other human activities, increasing atmospheric concentrations of the gas.

Rabbits typically live in burrows underground that they dig themselves or repurpose from other animals. They use these burrows for protection from predators and extreme weather conditions. In captivity, rabbits are usually provided with hutches or cages as shelter.

Matter cycles through the biosphere through various processes such as photosynthesis, respiration, decomposition, and nutrient cycling. These processes involve the movement of elements like carbon, nitrogen, phosphorus, and water between living organisms and the environment, ensuring that these elements are continuously recycled and reused by different organisms in the ecosystem.

Yes, for example: Say someone brought a type of fish (cod maybe) to Alaska that does not naturally live there. Then the cod spreads to salmon spawning grounds. So you have large hungry cod against baby salmon, who wins? The cod right. So the cod eats eventually all the baby salmon. This is not the best example but in a long while the salmon numbers will go down

down

down

Then with not enough to reproduce you have no more salmon. Still don't get it? Look below

Hungry big cod+ little baby samon= less to reproduce= less babies which are eaten

Charles Elton is known for his work on trophic levels and food chains in ecological systems. He developed the concept of the "pyramid of numbers" to illustrate the relationship between different levels of a food chain. Elton's research helped to shape our understanding of how energy flows through ecosystems and the importance of maintaining ecological balance.

Advantages of nature include promoting physical and mental well-being, providing a sense of tranquility and connection with the environment, and offering opportunities for recreation and relaxation. Disadvantages can include exposure to weather-related risks, potential hazards from wildlife, and limited access to modern amenities or services.

An increase in population can lead to more competition for resources among animals at the top of the energy pyramid. This can result in reduced food availability, increased stress, and sometimes even lead to changes in behavior or habitat use in those animals. Additionally, higher human populations can lead to habitat destruction and fragmentation, further impacting the animals at the top of the energy pyramid.

A limpet is a consumer. Limpets are herbivores that feed on algae, which makes them primary consumers in the food chain.

No. This is because of the 10 percent rule. You only get 10% of the energy from the animal/plant consumed. For each trophic level the actual amount of energy absorbed is much less than the trophic level before it. For example, the grass gets 10% of the energy from the sun. The zebra gets 10% of the 10% that the grass got. The hungry lion only gets 10% of the little 10% of the 10% from the grass that the zebra get. It's a little confusing, but it does make sense. Lets do it in terms of muffins. You have 100 muffins. I'm in the next trophic level, so I get 10 muffins. The next tropic level above me only gets 1 muffin. The trophic level above that one only gets 0.1 of that muffin.

No, removing animals from the carbon cycle would not stop the cycle. While animals play a role in the carbon cycle through respiration and decomposition, the cycle would continue through other processes such as photosynthesis by plants, decomposition by microorganisms, and geological processes.

The prey (an animal that is caught for food).

Abiotic factors, such as temperature, water availability, and sunlight, are considered limiting factors whose effects are not influenced by population density. These factors directly affect the growth and survival of organisms irrespective of how many individuals are present in a given area.

Most antibiotics will have an expiration date printed on the packaging. If there is no expiration date or if it has passed, you should consult a pharmacist or healthcare provider for guidance. Using expired antibiotics could potentially be ineffective or even harmful.
