The given blank can be filled with dinosaur footprints.  

In the Precambrian, the sedimentary rocks deposition took place in the Blue Ridge Province of Virginia, however, no fossils have been positively determined from these deposits. The Paleozoic rocks are well documented in Virginia. The occurrences of shallow area deposition were obstructed by subsequent periods of erosion and mountain-building incidents.  

The withdrawal of the widespread shallow regions of the Paleozoic left much of the state exposed at the time of Mesozoic and Permian. In central Virginia, fossils of freshwater fish, dinosaur footprints, and insects are found in the rift basin deposits of the Triassic.

community

Explanation:

Community refers to a group of populations of different species that live together in a defined habitat. These species exhibit interdependence for one or other resources. It is a level of the ecological organization just above the population and consists of hundreds of different types of organisms of various species.

Butterflies and flowering plants belong to different species. Butterflies are dependent on these plants for food. Therefore, these two together represent two populations of different species living together in habitat and are an ecological community.

In a rainforest food chain, caterpillars and butterflies eat orchid plants. Toucans eat the caterpillars and butterflies. Leopar
Tems11 [23]

Answer:

The caterpillars gain energy directly from the orchids

Explanation:

Earth maintains the flow of nutrients in the form of cycles and linear sequence in which the nutrients in the form of matter and energy flows from one organism to another and one sphere to another sphere.

One such flow of nutrients in the form of matter and energy can be observed in the organisms when one organism feed upon another and gain energy. This flow of matter and energy is called a food chain.  

The energy flows in this food chain through ten percent rule which states that only ten percent of energy can be transferred to next trophic level, therefore, the organism at the lowest level will have the highest amount of energy.

In the given question, the caterpillars can be considered as primary consumers which gain energy from the orchid plants directly and thus is the most appropriate answer.

List the 8 elements of weather that are observed for making weather forecasts
NemiM [27]
Temperature, precipitation, wind direction, wind speed, clouds (types and altitudes), atmospheric pressure, humidity, and visibility. It really depends on what you're forecasting but most of the time forecasters look for high/low-pressure systems in weather models and behavior of various winds at levels such as jet stream.
