Why is it important to design field studies that will not make wild animals associate humans with food?
Animal behaviorists have found that animals gain from developing bonds with trustworthy humans, but doing so calls for a lot of motivation and understanding about the animal's behavior.
What is animal behavior?The scientific study of non-human animal behavior is called ethology, and it often focuses on behavior in natural settings and sees behavior as an evolutionary adaptive quality.
Animal behavior is an animal's response to stimuli, and there are both acquired and intrinsic types of animal behavior.
Dogs who have been trained to obey commands are an example of animal behavior. In contrast, inherent behavior includes mating cues like bird crowing and peacock dancing before a storm.
Animals benefit from forming relationships with dependable humans, according to animal behaviorists, although doing so requires a lot of drive and knowledge of the animal's behavior.
Anyone lacking sufficient motivation or missing the necessary knowledge could suffer considerable harm if they attempted to interact with the animal.
Thus, it is important to design field studies that will not make wild animals associate humans with food.

What prior species of hominids did homo sapiens encounter in europe approximately 40,000 years ago?.
Answer:
Neanderthals
Explanation:
Homo sapiens encountered neanderthals in europe and had offspring.
The prior species of hominids that Homo sapiens encounter in Europe approximately 40,000 years ago is Neanderthal.
What is species?
Species is the term that is used to classify different organisms. Species is the second last classification, which means most similar organisms are present in this classification. The traits are mostly similar in these organisms.
While the form of the head and face was not significantly different from that of current humans, there were still quite a few distinctions. Most notably that of the modern human head, which is shorter and has a less prominent facial front. Neanderthal was a former human.
Therefore, the Neanderthals are the ancestors of Homo sapiens, who first encountered them in Europe some 40,000 years ago.

a) Based on this information and the food chain below, what are the implications of
not taking immediate steps to reduce CO2 emissions in the atmosphere? (2 points)
algae → snails — crabs — salmon → man
b) Because killer whales are at the top of many food chains, it may seem as if they
are not at risk of starving if seals die off. Why is this not necessarily true? (2 points)
Answer:
a) Higher carbon dioxide levels means a rapid growth of Algae, especially toxic blue-green algae that can float to the surface of the water. This growing amount of Algae will expand across the ocean and clutter it. Harmful algal blooms can be harmful to aquatic life, as some produce toxins that can make animals sick, while others can die off in large quantities and deplete oxygen in the water when they decompose. Snails, specifically aqaurium snails, crabs, and salmon do feed on Algae, which could control it to a degree. However, as the ocean becomes more acidic, it could dissolve the shells of crabs and snails, which will cause them to cook in the sun, and therefore die out. As for salmon, studies showed that high CO2 concentrations disturb fish acid-balance, induce stress response, increase nephrocalcinosis incidence, energy metabolism, and feed conversion ratio, and reduces body condition factor, feed intake, and growth. Fish in this condition are very vunerable to dying despite food being all around them. Additionally, fish in those conditions are not suitable for consumption, which means less food for mankind.
b) This is not true. Although they eat sharks, whales, and dolphins, that is just occasional. Seals are their primary meal. As the killer whale is a consumer, it cannot provide food/energy for itself, therefore relying on organisms below it on the food chain. The killer whale predominately consumes seals, being it’s only large predator, killer whales are crucial to the stabilisation of seal population.
