Ecologists use indirect observation to estimate population size when direct counting is impractical or impossible, such as in densely populated or elusive species. This method involves assessing signs of presence, like tracks, nests, or feces, to infer population size and distribution. Indirect observations can also be useful in sensitive habitats to minimize disturbance to wildlife. Overall, this approach provides valuable insights while maintaining ecological integrity.
A full grown dolphin's length would be 7ft but there are some that have as long as up to 12ft. An estimate of weight would be around 450-600 pounds.
Gallons is a liquid measurement and pounds are a solid measurement. A close estimate would be almost five gallons.
conservative estimate, using the average weight of a humming bird and average lift, i came up with approximately 13,608
There is an unestimated amount of hairs on a lion because every lion has a different number of hairs. If i were to estimate it it would probably be over a million.
His observations indicated that the size of the beaks of finches were responding to the ever changing environment. For instance, if the environment favored large nuts, finches born with powerful beaks capable of cracking them open would survive better than those with smaller beaks.
Direct observation means looking at it with your own two eyes, feeling it with your fingers (or other body parts), directly hearing it with your ears or directly tasting it with your tongue. Indirect observation means not sensing the object of observation directly but by observing the effects it has on its surroundings. An example of indirect observation might be seeing footprints in the snow and using this as evidence that snow leopards are in the area. Direct observation would be seeing the leopard itself.
If the bubbles produced can relight a glowing splint or support combustion, it would provide indirect evidence that the bubbles are oxygen (O2). This is because oxygen is required to support combustion.
Direct observation is an instance in which you use one of your senses: sight, smell, taste, touch, hearing, to experience an event that happened in your presence. An indirect observation is basically the opposite of a direct observation in that you observe something after it has happened. Example of a direct observation would be seeing a burning fire, feeling its warmth and smelling the fumes. Or perhaps your eyes get watery from the smoke. The indirect observation would be coming upon an empty campsite and seeing the burnt logs and ashes.
The members of a population may be small or hard to find. Indirect observation is when it would be easier to observe what the animals left behind, like a nest or tracks, rather than the organism themselves. Ex: If there are 120 nests in an area, you can find the number of swallows by multiplying 120 by , or 480 swallows.
Broadly speaking yes. The difference would be that generally we would say that the ecologist has a career and the environmentalist supports a movement.

Direct observation is an observation made by using your senses (hear, see, touch, taste, feel). In this case, the observer records directly what that are seeing. Contrary, an indirect observation is an observation made by observing the effects on the present surrounding. In this case, the observer would use the recordings of others (including self observation). In other words, what you can see directly versus what you can infer from another observation. Direct observation, as an example, would be seeing a dog and observing that he is there. Indirect observation, as an example, would be seeing the dog's paw prints in the snow and observing that he had been there.
If the bubbles do not relight a glowing splint, it would suggest they are not oxygen. Oxygen is a gas that supports combustion, so if the bubbles do not allow the splint to reignite, it indicates they are not oxygen.

ecologist
A person who studies animals and the way they interact with their environment is both an ecologist and a zoologist. Ecologists study the interactions of organisms within their environment, while a zoologist studies animals.
I would describe such a scientist as an environmental scientist.
