Two students went for a walk in a small pond ecosystem where they observed several interactions. Read their observation below to find out what they saw. Small fish were found feeding on the green algae. Fish, frogs and snails were harder to find after a family of raccoons came to the pond. Fish and frogs were observed catching insects. As the amount of green algae increased, more insects and snails came to feed on it. A sample of the pond water contained bacteria.
Answer:
a food web
Explanation:
What they saw was a food web, which refers to connections of food chains showing how energy and nutrients are transferred from one organism to the other.
In this example, we observe there are seven organisms (fish, algae, snails, insects, frogs, raccoons + bacteria contained in the pond) in focus here.
The green algae are Producers (because it produces its own food, not dependant on others)
The bacteria act as Decomposers. ( because they process organic waste into meaningful natural nutrients again)
The other organisms are Consumers. (because they are dependant on others for their nutrition).

What trend in the complexity of life over time is seen through the fossil record?
Most animal and plant species we see in the fossil record are extinct, or no longer living. In fact, of all the species that ever lived, 98% are extinct. Animals and plants become extinct over time as a result of natural processes. Their habitat might change or a disease might wipe out a species.
The trend of extinction and difference in body parts in the complexity of life
over time is seen through the fossil record
Fossils refers to remains of living organisms which have been replaced in the form of rock particles due to its presence in the soil for a long period of time.
The fossils contain an understanding of the structures and characteristics
the animals had which is then compared to its present structures. This helps
to explain how the animals adapted to climate change through changes in
the structure, shape of parts of the body.
It also tells the location of animals and their different movements in response to challenges faced in the ecosystem.

What can we NOT learn from the fossils found in rock strata?
Answer:
The location of fossils in rock layers provides evidence of Earth's past landscapes. It is hard to guess the age of rock. Scientists have to act like detectives, piecing together a mystery to determine how long ago rocks formed. Fossils found in a particular rock layer help scientists determine the age of the rock.
Explanation:
so anything besides of what I just said...
Hope this helps you, may i have brainliest please.
What we cannot learn from the fossils found in rock strata is: the diversity of organisms at a certain location or during a certain time period.
Rock strata (layers) that are found in various parts of the world are usually different from one another because they all comprises distinct Earth's geological history, which are referred to as fossils.
A fossil can be defined as the mineral impression or remains of both living and non-living organisms that are prehistoric in nature.
This ultimately implies that, fossils are ancient organisms such as plants and animals that were formed into rocks.
Some of the information that can be learnt from the fossils found in rock strata are:
The time when a species of an organism became extinct.How a particular organism has changed over time.The exact age of each individual fossil through the use of radiometric dating.Read more: https://brainly.com/question/22044539

4a. By 40-60 years after farm fields had been abandoned, the amount of herbaceous plants
decreased. Give one reason why the amount of herbaceous plants decreased as the amount of trees
increased.
Answer:
See the answer below
Explanation:
The amount of herbaceous plants in an abandoned farm field will keep decreasing with time and the amount of trees would be increasing instead due to successional forces.
Succession refers to the gradual change in the species structure of a community with time. Early successional species usually colonize new habitats and with time, they are replaced with late successional species until a relatively stable community, climax community, is established.
Herbaceous species on abandoned farmland represent early successional species and as time goes on, they will be replaced by mid to late successional species in the form of shrubs and trees until a relatively stable community is formed. Hence, herbs would be decreasing while trees would be increasing.
